Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio 6.1 6.1.1 Audio I/O switching INPUT SELECT (INPUTSEL) 3. SAP (SAP input). TDA9614H For the audio FM circuitry eight different audio signals can be selected. The selection made here for hi-fi is also available for the linear audio circuitry. 1. TUNER (stereo input; internal tuner of VCR). 2. CINCH (stereo input; connection to hi-fi set). 3. EXT1 (stereo input; TV SCART1). 4. EXT2 (stereo input; decoder, 2nd VCR SCART2). 5. EXT3 (stereo input; front CINCH for e.g. camcorder). 6. SAP (mono input; `Second Audio Program' audio carrier for NTSC or conventional FM carrier with NICAM reception). 7. NORMAL (linear audio; [playback] signal of linear audio). When inserting a new video signal in an old audio/video recording the hi-fi audio track is erased. This setting can keep the current audio available on the hi-fi track by copying the (playback) linear audio signal to the hi-fi track during video insert. 8. EXT3/ST (input mix; mono EXT3 on left, mono hi-fi on right channel). For linear audio use see Section 6.1.2. 6.1.2 NORMAL SELECT (NORMSEL) This setting enables simultaneous recording of the NTSC SAP signal on the linear track and TUNER stereo on the audio FM track. When receiving a NICAM audio signal, the linear audio can be used as a `backup' track when received television signals are weak. 4. TUNER LEFT (left channel [language 1] of TUNER input). When receiving dual language transmissions the main language (language 1) can be recorded on linear audio. Note that if the SAP input is not used it can be connected to the right TUNER channel, enabling language selection for linear audio. 6.1.3 VOLUME L/R; AGC The volume controls are mainly intended for level adjusting of the audio signals to be recorded on the hi-fi track, however using the `VOLUME' setting in the Normal Select it can also be used to control linear audio. The volume controls have a control range of +14 dB to -49 dB in 1 dB steps and a full mute. Because the volume controls are I2C-bus controlled their actual behaviour is defined by the VCR's software. For instance user control can be `volume only', `left + right', `volume + balance' or the setting can be defined by a `digital AGC' software loop using the signals at the DC (VU meter) outputs. The linear audio level can be controlled by an AGC circuit, which can be switched off when desired. In most cases the AGC should be used at all settings of the Normal Select except for `VOLUME'. 6.1.4 AUDIO FM OUTPUT MUTE (AFOMUTE); NORMAL OUTPUT MUTE (NOMUTE) For linear audio four settings can be selected: 1. INPUTSEL (mono signal from input select). This is the `standard' setting. The signal source selected with the input select is led to the linear audio circuit. The linear audio AGC should be switched on. 2. VOLUME (mono signal from [hi-fi] volume control). The signal source selected with the input select has now volume control, the linear audio AGC should be switched off. This setting is for use with `audio dubbing': inserting a new audio signal on the linear track in an old audio/video recording. A special audio dubbing feature is now possible by selecting `input mix' EXT3/ST in the input select. This setting enables us to use the VCR as a mixer console: an audio source connected to EXT3 (front CINCH) can be adjusted and mixed together with the original hi-fi playback signal, using the left (EXT3) and right (hi-fi playback) volume controls. The audio output signal of the audio FM circuit can be muted with AFOMute, the linear output signal can be muted using NOMute. If one of these signals is not used as an output (or input) signal it is best muted to further minimize crosstalk. 6.1.5 OUTPUT SELECT (OUTSEL) This block is the `main' output select function, possibly functional on all outputs. Each output however has some means to override this selection for its own output signal, to implement extra features. Eight selections are possible and they are shown in Table 1. 1995 Mar 21 9 Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio Table 1 Output select possibilities REMARK hi-fi stereo hi-fi left hi-fi right linear audio linear and hi-fi linear and left linear and right mute DESCRIPTION audio FM output signal left and right channel audio FM output signal left channel (language 1) audio FM output signal right channel (language 2) linear audio mix of audio FM stereo and linear audio mix of audio FM left channel and linear audio mix of audio FM right channel and linear audio TDA9614H SELECTION STEREO(1) LEFT RIGHT NORMAL NOR + ST NOR + L NOR + R MUTE Note 1. STEREO is the `standard' setting, LEFT and RIGHT are for language selection. Using the tuner as input or output signal (record or loop-through of audio FM) the VCR can automatically switch from stereo to left (language 1) when a `dual language' transmission is received. If the VCR is in playback mode and no hi-fi track is present (checking bit AFOM via the I2C-bus or using the level at pin 11) the VCR can switch the output select to NORMAL (or let the IC do this automatically by setting bit AUTN). If a hi-fi track is present the user may want to switch to LEFT and RIGHT if the recording made was a `dual language' recording. Furthermore the user may want to switch from a hi-fi selection to NORMAL, e.g. when a complete audio remix has been created on the linear track using `audio dubbing' (see Section 6.7). `Audio dubbing' can also be used to re-record the linear track with e.g. only commentary. Combined playback of this commentary together with the original hi-fi sound is then possible by means of a mix mode. 6.1.6 RF CONVERTER MUTE (RFCMUTE) The RFC output is a mono output derived from the output select, its output signal can be muted. 6.1.7 LINE SELECT (LINESEL) The line output select is normally connected to both CINCH (hi-fi set) and television (SCART1). Normally the audio signal from the output select will be available at this output, but three extra selections are possible and they are shown in Table 2. Table 2 Extra line select possibilities DESCRIPTION linear audio, useful for monitoring during `audio dubbing' audio from input EXT2 audio from input EXT3 SELECTION NORMAL EXT2(1) EXT3(2) Notes 1. A signal from a source at EXT2 (laser disc or second VCR) can be connected to a television set at line out. Because this is a direct connection from the input to the line output buffers it is fully independent of any mode setting of the IC. Connection of a `Pay-TV' decoder box to EXT2 and using this selection together with selecting EXT1 in the decoder select enables combined use of the decoder box by both TV and VCR. In Europe, use of the SCART connector `status line' can automatize this switching. 2. Direct audio connection from input EXT3. If the line 2 outputs and EXT3 inputs are not used for external connections a built-in karaoke unit or sound processor can be inserted between line 2 and EXT3. 1995 Mar 21 10 Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio 6.1.8 DECODER SELECT (DECODESEL) TDA9614H both hi-fi audio channels, independent from the setting of output or headphone select. For this mode the selection STEREO can be made. 6.2 6.2.1 Linear audio circuits RECORD/LOOP-THROUGH The line 2 output is normally connected to a decoder box or e.g. a second VCR (SCART2). Normally the audio signal from the output select will be available at this output, but three extra selections are shown in Table 3. Table 3 Extra decoder select possibilities DESCRIPTION audio from input TUNER audio from input EXT1 audio from input EXT3 SELECTION TUNER(1) EXT1(2) EXT3 Notes The signal selected with the normal select can be level controlled in the AGC block. If wanted this AGC can be switched off using bit AGCN. The audio signal is thereafter DC decoupled using a capacitor between pin 29 (LINOUT) and pin 28 (LININ). From here on the signal goes to the output select and (in the event of record mode) to the record equalizer. The record equalizer is a non-inverting amplifier with a gain of +12 dB, consisting of an opamp with feedback resistors, and acts as a pre-correction filter for the tape and head characteristics. The inverting input of the opamp is connected to pin 31 (RECEQ), its output to pin 33 (RECOUT). The circuit externally connected between pin 31 and ground defines the transfer of the record ( 1200 + Z ) equalizer with equation: A = 3.98 x ----------------------------Z Where: Z is the complex impedance of the external circuit. Two equalizings can be used, switching additional circuitry to ground with pin 30 (EQSW) in long play or extended play (I2C-bus: LP = 1). Instead of the hi-fi circuit, linear audio has two loop-through modes: * Loop-through playback * Loop-through record. The only difference between Loop-through record and record is the RECOUT output, which is muted. The LINREC output (pin 32) is used to drive the external high-voltage switch and possibly the bias oscillator. The LINREC voltage has a small internal delay to be non-overlapping with the internal switching to playback mode. This ensures that no bias voltage will appear at the PBIN input while the IC is in playback mode. 6.2.2 PLAYBACK 1. Enables the use of a decoder box (connected to line 2 [EXT2]) by the VCR. 2. Decoder box connection to television set (See Section 6.1.7). 6.1.9 HEADPHONE SELECT (HPSEL) The headphone output will normally carry the output select signal, however three more selections are possible and shown in Table 4. Table 4 Extra headphone select possibilities DESCRIPTION left hi-fi channel right hi-fi channel linear audio, useful for monitoring the recording by `audio dubbing' SELECTION LEFT(1) RIGHT(1) NORMAL Note 1. The selections LEFT and RIGHT make it possible to select a different language for the headphone as for the line outputs. A possible implementation is to invert always a language selection made at the output select. 6.1.10 HEADPHONE VOLUME The headphone volume control has a control range of +16 dB to -47 dB in 1 dB steps and a full mute. 6.1.11 DC SELECT (DCSEL) The VU meter output is normally connected to the headphone select, but can also be switched to STEREO (hi-fi stereo, before the output select). When using the VU meter output signal to implement a `digital AGC' (read the level at the DC output, and adjust the VOLUME L/R controls accordingly) it is necessary to have information of 1995 Mar 21 11 The signal coming from the head is amplified and can be level controlled in 16 steps of 1 dB. This setting can be used to adjust for spread or nominal difference in head output level. Afterwards, the signal is frequency corrected in the playback equalizer. This equalizer includes the two standard VHS equalizing settings of 3180 and 120 s Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio (standard play: LP = 0) and 3180 and 170 s (Long Play: LP = 1). The signal is DC decoupled and routed to the output select via pins 29 and 28. When switching to or from playback the signal should be muted shortly using the Normal Output Mute (NOM) to prevent audible clicks caused by offset differences of the playback amplifier and AGC. 6.3 6.3.1 Audio FM circuits RECORD/LOOP-THROUGH TDA9614H low-pass filtered audio signal is expanded in the noise reduction. If the left channel carrier at FMIN falls below the mute level of 4.2 mV (RMS value) the audio signal is muted in front of the low-pass filter. This is achieved by comparing the left channel level detector signal with an internal reference. The mute timing is fixed by a capacitor at the CMUTE pin. If the level at CMUTE rises above a certain threshold, the PBMUTE bit is set. This will mute the audio signal. If bit AUTN has been set, the output selection will automatically switch to NORMAL mode. The left channel level detector output is also available at pin ENVOUT. An AGC correction voltage is added at this pin, such that the ENVOUT voltage indicates the left channel FM-carrier level even within the AGC-range. The ENVOUT voltage can be used for auto-tracking of the FM-audio heads. In the event of drop-outs in the incoming FM signal, the left channel level detector is also used to activate the sample-and-hold. This drop-out cancellation is only active if bit DOC has been set. 6.3.3 AUTOMATIC CALIBRATION After low-pass filtering and signal compression in the Noise Reduction (NR) the audio signal is available at AFNL and AFNR. Through a DC-decoupling capacitor the compressed audio signal is fed to an audio clipper at AFML and AFMR. Subsequently, the audio signal is FM-modulated on a RF-carrier using an integrated current-controlled oscillator (CCO). Each CCO (L and R) requires an external resistor (RCCOL/R) for temperature stability. Through automatic calibration both the oscillator centre frequency and FM-deviation are adjusted. After low-pass filtering and summation of the two RF-carriers, the FM signal is available at FMOUT during record. During loop-through the FMOUT pin is inactive. The RAF pin reflects the status of the RAF-bit when it is used as output pin. In this case it is meant to switch the head amplifier between record and playback position. It can also be used as an input pin to overrule the RAF-bit thereby forcing the IC in record or playback/loop-through position. 6.3.2 PLAYBACK By means of bit CALS the two integrated oscillators and bandpass filters can be calibrated in Loop-Through (LT) or record (REC) mode. Normally this will be done after start-up of the VCR. After setting of bit CALS the calibration procedure is automatically executed as shown in Fig.4. The calibration starts at the first negative edge of HID after CALS has been set. During the LOW period of HID (20 ms for PAL) the number of oscillator cycles is compared to a certain value stored in a Read Only Memory (ROM). Therefore, the final oscillator frequency is proportional to the inverse of the HID LOW-time. This means that an error of 1 s in the HID LOW-time will result in an additional frequency error of approximately 100 Hz. The maximum number of required HID cycles for one complete oscillator calibration is six, which is equal to 240 ms. After both oscillators have been calibrated the bandpass filters are calibrated using the right channel oscillator as reference frequency generator (1.6 MHz for PAL). This will take <10 ms. Bit CALR is set to 1 if the calibration has been executed successfully. CALR is 0 if: * A Power-On Reset (POR) has occurred. * The calibration is running. * The initial oscillator and bandpass frequencies are too low or too high for a successful calibration. The two FM modulated RF carriers, presented at FMIN, are fed to an AGC circuit. The AGC operates on the peak level of the added BPF output signals. As a result, the input signal of the BPFs is kept constant for FMIN voltages >30 mV (RMS value) both carriers added. In this way the dynamic range of the integrated BPFs is optimally used over a large input signal range. Subsequently, the RF carriers are bandpass filtered using two integrated BPFs. These bandpass filters are automatically calibrated as described in Section 6.3.3. An external resistor (RBPF) is required for temperature stability. The filtered input signals are fed to a limiter. The limiter output signal is demodulated by means of a PLL demodulator. The LF audio signal is fed through a sample-and-hold circuit to suppress head-switching noise. The demodulated audio is available at AFML and AFMR. Through a decoupling capacitor the audio signal is applied to an audio low-pass filter at AFNL and AFNR.

If CALS is reset during CALR = 0, the calibration will be stopped if it was not finished yet. If required, a new calibration can be started using CALS. WARNING: the IC should not be calibrated in a test or standby mode. 6.3.4 PAL/NTSC MODE WARNING: A change of PB to REC, LT to REC and PAL to NTSC should not be combined in one transmitted byte. The PAL to NTSC transition should be preceded by the PB to REC or LT to REC transition. 6.4 I2C-bus Depending on bit NTSC the IC is calibrated in PAL or NTSC mode using bit CALS. After an automatic calibration the oscillator frequencies can be switched between PAL and NTSC using bit NTSC. This centre frequency shift is done without automatic calibration. During playback (PB) or loop-through (LT) a change in bit NTSC will automatically calibrate the bandpass filters again. This will take <10 ms. The TDA9614H is controlled via the 2-wire I2C-bus, in accordance with the I2C-bus specification. As slave receiver for programming there is one module address, with R/W bit = 0, a subaddress byte and eight data bytes. If more than one data byte follows the subaddress, these bytes are stored in the successive registers by the automatic address increment feature. As slave transmitter (R/W bit = 1) there is one read byte. 1995 Mar 21 13 Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio Table 5 TDA9614H addresses and data bytes NAME Slave address byte Subaddress bytes 00 to 07 Control byte (subaddress 00) Main select byte (subaddress 01) Secondary select byte (subaddress 02) Left volume byte (subaddress 03) Right volume byte (subaddress 04) Headphone volume byte (subaddress 05) Install byte (subaddress 06) Test byte (subaddress 07) Read byte (address B9) Note 1.

The RAF bit can be overruled externally by applying a low-ohmic voltage to the RAF I/O (pin 12) either logic 0 or logic 1 (0 or +5 V). The actual mode of the IC is determined by the level measured at this pin, enabling fast switching between record and playback/loop-through. 2. The two record modes are equal, only differing in their reaction to forcing RAF LOW at the RAF I/O pin; the status of the IPAF bit determines whether the IC is switched to the playback or loop-through mode.

With bits IS2 to IS0, the stereo input signal is selected which is led to the hi-fi processing. One out of five stereo sources can be selected. The five stereo inputs differ in their connectivity; with bits NS1 and NS0 tuner left (TUNL; pin 2) can be selected as linear audio input source, with bits LOS1 and LOS0 Normal, Ext2 and Ext3 are directly connectable to Line out and to DOS1 and DOS0 Tuner, Ext1 and Ext3 are directly connectable to decoder out (2nd Line Out). 2. Remark: when using the selections Normal or Dub Mix be aware of signal loops (which should be avoided) because this can lead to large audio oscillations. 3. The selection Dub Mix is a special function in which a mono signal derived from the Ext3 inputs (12EXT3L + 12EXT3R) is led to the left input and a mono signal derived from the audio FM output (12L + 12R) is led to the right input channel. This function can be used for audio dubbing using the volume controls as a mixing desk. Table 16 Bits NS1 and NS0; note 1 NS1 0 0 1 1 Note 1. With bits NS1 and NS0 the input signal is selected for the linear audio circuit. When a stereo input source is selected, a mono signal is made by adding the left and right channel. Furthermore two independent selections can be made (the mono input SAP or the left channel of tuner e.g. for dual language). If in the volume mode the built-in AGC circuit is switched off by using bit AGCN, the audio level can be controlled by the left and right volume controls (VLx and VRx). 1995 Mar 21 17 NS0 0 1 0 1 MODE Input Volume SAP Tuner L DESCRIPTION linear audio input source is equal to hi-fi input [por] linear audio input source is equal to hi-fi input, inclusive volume control additional mono input (SAP; pin 1) is selected left channel of tuner input is selected IS1 0 0 1 1 0 0 1 1 IS0 0 1 0 1 0 1 0 1 MODE Tuner Cinch Ext1 Ext2 Ext3 SAP Normal(2) Dub Mix (2)(3) CINL and CINR EXT1L and EXT1R (e.g. SCART1; TV connector) EXT2L and EXT2R (e.g. SCART2; decoder connector) EXT3L and EXT3R (e.g. front cinch) additional mono input (SAP; pin 1) output from linear audio (LININ; pin 28) mixing of EXT3 input with hi-fi output signal SELECTED INPUT SOURCE TUNL and TUNR [por] Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio Table 17 Bits OSL, OSR and OSN; note 1 OSL 1 1 0 0 1 1 0 0 Note OSR 1 0 1 0 1 0 1 0 OSN 0 0 0 0 1 1 1 1 left right mute mixed stereo mixed left mixed right normal MODE stereo DESCRIPTION LEFT at left channel; RIGHT at right channel [por].

LEFT + NORMAL added at both left and right channels. RIGHT + NORMAL added at both left and right channels. NORMAL (is linear audio) at both left and right channels. 1. The bits OSL, OSR and OSN provide eight output select functions. LEFT and RIGHT are the left and right hi-fi channels; NORMAL is the linear audio channel (LININ; pin 28). This selection is normally output at line out (LINEL and LINER), RFCOUT (pin 18), decoder out (LINE2L and LINE2R), headphone out (HPOUTL and HPOUTR) and DC out (DCOUTL and DCOUTR). However line out can be overruled by bits LOS1 and LOS0; decoder out can be overruled by bits DOS1 and DOS0, headphone out (and DC out) can be overruled by bits HSL and HSR and DC out can be overruled by bit DCS. Remark: if AUTN = 1 (see Section 6.11) the output select modes stereo, left and right will be forced to normal as long as the audio FM circuit is in playback mode and the internal PB mute signal is generated (no hi-fi track on tape). The status of this internal mute signal can be read by bit PAFM (see Section 6.13). 6.8 Secondary select byte Table 18 Bits of secondary select byte BIT HSL HSR DCS RFCM LOS1 and LOS0 DOS1 and DOS0 DESCRIPTION Headphone Select Left; see Table 19 Headphone Select Right; see Table 19 DC Select; see Table 20 RFC Mute; see Table 21 Line Output Select 1 and Line Output Select 0; see Table 22 Decoder Output Select 1 and Decoder Output Select 0; see Table 23 1995 Mar 21 18 Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio Table 19 Bits HSL and HSR HSL 1 1 0 0 HSR 1 0 1 0 outsel left right normal MODE DESCRIPTION TDA9614H Headphone signal set by the output selection [por]. LEFT at both headphone out left and right. RIGHT at both headphone out left and right. NORMAL (is linear audio) at both headphone outputs. Normally the headphone output signal is set by the output selection OSL, OSR and OSN (see Table 17). Furthermore three independent selections can be made: LEFT hi-fi channel, RIGHT hi-fi channel (language selection) and NORMAL (e.g. monitoring an audio dubbing recording). These headphone selections are also active for the VU meter output (DC out), unless bit DCS = 1. Table 20 Bit DCS DCS 0 1 Note 1. The signal at DC out (DCOUTL and DCOUTR; pins 23 and 24) is normally the signal which can be listened to by the headphone. For use in concepts with digital AGC (using the DC output signal to control the left and right volume settings), an independent selection to hi-fi stereo can be made. Table 21 Bit RFCM RFCM 0 1 Note 1. The audio signal at RF converter out (a mono version of the signal selected with the output select with overload AGC) can be independently muted.

Test number 31 (TST4 to TST0 = 11111) is a special setting which can be used to change the internal linear audio playback equalization to non-standard settings as shown in Table 38. 1995 Mar 21 27 Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio Table 38 Linear audio playback equalization non-standard settings SETTING Standard play (LP = 0) Long play (LP = 1) MODE 3180 and 120 s 2544 and 96 s 3180 and 170 s 2731 and 146 s 6.13 Read byte not selected selected not selected selected TEST NUMBER 31 TDA9614H Table 39 Bits of read byte BIT CALR PAFM POR Table 40 Bit CALR; note 1 CALR 0 1 Note 1. If CALR = 0, bandpass filters and oscillators have not been calibrated successfully. When an automatic calibration is started by bit CALS, the end of the calibration cycle can be checked via this bit. If for some reason a successful calibration can not be made within the available adjustment range, e.g. if no HID signal is available, CALR will remain logic 0. After calibration the adjustment will be held for as long as the digital supply voltage (VDDD) is available. Table 41 Bit PAFM; note 1 PAFM 0 1 Note 1. When the hi-fi processing is in playback mode but no Audio FM input signal is found, the IC generates an internal mute signal which mutes the noise signal coming from the demodulators. The status of this mute signal can be read via bit PAFM. This signal however is only valid with the hi-fi circuit in playback (RAF = 0 and IPAF = 0). Table 42 Bit POR; note 1 POR 0 1 Note 1. When the IC is switched on, or a power dip occurs on the digital supply (VDDD) line, a Power-on Reset signal is generated which resets the IC's I2C-bus registers and the auto-calibration circuit. If such a situation has occurred after the last time the read byte has been read, bit POR = 1. After reading the read byte POR is reset to logic 0. - POR generated MODE - POR pulse is generated since last read. DESCRIPTION MODE AFM available no AFM carrier DESCRIPTION Audio FM signal is detected at FM input. No audio FM signal detected; hi-fi processing is muted. MODE not calibrated calibrated DESCRIPTION IC has not been auto-calibrated [por]. IC has been calibrated successfully.

This output can be used to switch the audio FM head amplifier to playback and record. If accurate fast switching of the TDA9614H is needed, this pin can also be used as input. Thereby overruling the I2C RAF bit. To make this possible the RAF output is current limited. When using the RAF pin as output, no more than 35 A (LOW) and 185 A (HIGH) current may be drawn from this pin to assure that the mode of the TDA9614H is not changed. When using the RAF pin as input, the voltage source used must be capable of delivering at least 345 A (forced HIGH; >3.5 V) or sinking at least 65 A (forced LOW; <1.5 V). The external resistors to ground at pins RCCOL, RCCOR, RBPF and RFIX must have a tolerance of 5%. This is necessary to guarantee correct functioning of the IC. The temperature coefficient of the external resistors at RCCOL, RCCOR and RBPF have a direct influence on the related frequencies of the on-chip oscillators and bandpass filters. 1995 Mar 21 56 Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio 13 PACKAGE OUTLINE handbook, full pagewidth QFP64: plastic quad flat package; 64 leads (lead length 1.95 mm); body 14 x 20 x 2.8 mm TDA9614H SOT319-2 c y X 51 52 33 32 ZE A e E HE A A2 A1 Q (A 3) Lp L detail X pin 1 index wM bp 64 1 wM D HD ZD 19 20 e bp vMA B vM B 0 5 scale 10 mm DIMENSIONS (mm are the original dimensions) UNIT mm A max. 3.20 A1 0.25 0.05 A2 2.90 2.65 A3 0.25 bp 0.50 0.35 c 0.25 0.14 D (1) 20.1 19.9 E (1) 14.1 13.9 e 1 HD 24.2 23.6 HE 18.2 17.6 L 1.95 Lp 1.0 0.6 Q 1.4 1.2 v 0.2 w 0.2 y 0.1 Z D (1) Z E (1) 1.2 0.8 1.2 0.8 7o 0o Note 1.

Dwell times vary between 50 and 300 s according to method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 min at 45 C. 14.1.3 REPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING IRON OR PULSE-HEATED SOLDER TOOL) During placement and before soldering, the component must be fixed with a droplet of adhesive. After curing the adhesive, the component can be soldered. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder bath is 10 s, if allowed to cool to less than 150 C within 6 s. Typical dwell time is 4 s at 250 C. A modified wave soldering technique is recommended using two solder waves (dual-wave), in which a turbulent wave with high upward pressure is followed by a smooth laminar wave. Using a mildly-activated flux eliminates the need for removal of corrosive residues in most applications. 14.1.2 BY SOLDER PASTE REFLOW Fix the component by first soldering two, diagonally opposite, end pins. Apply the heating tool to the flat part of the pin only. Contact time must be limited to 10 s at up to 300 C. When using proper tools, all other pins can be soldered in one operation within 2 to 5 s at between 270 and 320 C. (Pulse-heated soldering is not recommended for SO packages.) For pulse-heated solder tool (resistance) soldering of VSO packages, solder is applied to the substrate by dipping or by an extra thick tin/lead plating before package placement. Reflow soldering requires the solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the substrate by screen printing, stencilling or pressure-syringe dispensing before device placement. 1995 Mar 21 58 Philips Semiconductors Preliminary specification Audio processor for VHS hi-fi and linear audio 15 DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values TDA9614H This data sheet contains target or goal specifications for product development.
