3 GENERAL DESCRIPTION
TDA6650TT; TDA6651TT
The TDA6650TT; TDA6651TT is a programmable 3-band mixer/oscillator and low phase noise PLL synthesizer intended for pure 3-band tuner concepts applied to hybrid (digital and analog) terrestrial and cable TV reception. The device includes three double balanced mixers for low, mid and high bands, three oscillators for the corresponding bands, a switchable IF amplifier, a wide band AGC detector and a low noise PLL synthesizer. The frequencies of the three bands are shown in Table 1. Two pins are available between the mixer output and the IF amplifier input to enable IF filtering for improved signal handling and to improve the adjacent channel rejection. Table 1 Recommended band limits in MHz for PAL and DVB-T tuners; note 1 RF INPUT BAND MIN. Low Mid High Note 1. RF input frequency is the frequency of the corresponding picture carrier for analog standard. The IF amplifier is switchable in order to drive both symmetrical and asymmetrical outputs. When it is used as an asymmetrical amplifier, the IFOUTB pin needs to be connected to the supply voltage VCCA. Five open-drain PMOS ports are included on the IC. Two of them, BS1 and BS2, are also dedicated to the selection of the low, mid and high bands. PMOS port BS5 pin is shared with the ADC. 4 ORDERING INFORMATION TYPE NUMBER TDA6650TT TDA6651TT 44.25 157.25 443.25 MAX. 157.25 443.25 863.25 MIN. 83.15 196.15 482.15 MAX. 196.15 482.15 902.15 OSCILLATOR
The AGC detector provides a control that can be used in a tuner to set the gain of the RF stage. Six AGC take-over points are available by software. Two programmable AGC time constants are available for search tuning and normal tuner operation. The local oscillator signal is fed to the fractional-N divider. The divided frequency is compared to the comparison frequency into the fast phase detector which drives the charge pump. The loop amplifier is also on-chip, including the high-voltage transistor to drive directly the 33 V tuning voltage without the need to add an external transistor. The comparison frequency is obtained from an on-chip crystal oscillator. The crystal frequency can be output to the XTOUT pin to drive the clock input of a digital demodulation IC. Control data is entered via the I2C-bus; six serial bytes are required to address the device, select the local oscillator (LO) frequency, select the step frequency, program the output ports and set the charge pump current or select the ALBC mode, enable or disable the crystal output buffer, select the AGC take-over point and time constant and/or select a specific test mode. A status byte concerning the AGC level detector and the ADC voltage can be read out on the SDA line during a read operation. During a read operation, the loop `in-lock' flag, the Power-on reset flag and the automatic loop bandwidth control flag are read. The device has 4 programmable addresses. Each address can be selected by applying a specific voltage to pin AS, enabling the use of multiple devices in the same system. The I2C-bus is fast mode compatible, except for the timing as described in the functional description and is compatible with 5, 3.3 and 2.5 V microcontrollers depending on the voltage applied to pin BVS.

FUNCTIONAL DESCRIPTION Mixer, Oscillator and PLL (MOPLL) functions
Bit BS1 enables the BS1 port, the low band mixer and the low band oscillator. Bit BS2 enables the BS2 port, the mid band mixer and the mid band oscillator. When both BS1 and BS2 bits are logic 0, the high band mixer and the high band oscillator are enabled. The oscillator signal is applied to the fractional-N programmable divider. The divided signal fdiv is fed to the phase comparator where it is compared in both phase and frequency with the comparison frequency fcomp. This frequency is derived from the signal present on the crystal oscillator fxtal and divided in the reference divider. There is
a fractional calculator on the chip that generates the data for the fractional divider as well as the reference divider ratio, depending on the step frequency selected. The crystal oscillator requires a 4 MHz crystal in series with an 18 pF capacitor between pins XTAL1 and XTAL2. The output of the phase comparator drives the charge pump and the loop amplifier section. This amplifier has an on-chip high voltage drive transistor. Pin CP is the output of the charge pump, and pin VT is the pin to drive the tuning voltage to the varicap diodes of the oscillators and the tracking filters. The loop filter has to be connected between pins CP and VT. The spurious signals introduced by the fractional divider are automatically compensated by the spurious compensation block.

5 V mixer/oscillator and low noise PLL synthesizer for hybrid terrestrial tuner (digital and analog)
It is possible to drive the clock input of a digital demodulation IC from pin XTOUT with the 4 MHz signal from the crystal oscillator. This output is also used to output 1/2fdiv and fcomp signals in a specific test mode (see Table 6). It is possible to switch off this output, which is recommended when it is not used. For test and alignment purposes, it is also possible to release the tuning voltage output by selecting the sinking mode (see Table 6), and by applying an external voltage on pin VT. In addition to the BS1 and BS2 output ports that are used for the band selection, there are three general purpose ports BS3, BS4 and BS5. All five ports are PMOS open-drain type, each with 15 mA drive capability. The connection for port BS5 and the ADC input is combined on one pin. It is not possible to use the ADC if port BS5 is used. The AGC detector compares the level at the IF amplifier output to a reference level which is selected from 6 different levels via the I2C-bus. The time constant of the AGC can be selected via the I2C-bus to cope with normal operation as well as with search operation. When the output level on pin AGC is higher than the threshold VRMH, then bit AGC = 1. When the output level on pin AGC is lower than the threshold VRML, then bit AGC = 0. Between these two thresholds, bit AGC is not defined. The status of the AGC bit can be read via the I2C-bus according to the read mode as described in Table 12. 7.2 I2C-bus voltage 7.3
TDA6650TT; TDA6651TT
Phase noise, I2C-bus traffic and crosstalk
While the TDA6650TT; TDA6651TT is dedicated for hybrid terrestrial applications, the low noise PLL will clean up the noise spectrum of the VCOs close to the carrier to reach noise levels at 1 kHz offset from the carrier compatible with e.g. DVB-T reception. Linked to this noise improvement, some disturbances may become visible while they were not visible because they were hidden into the noise in analog dedicated applications and circuits. This is especially true for disturbances coming from the I2C-bus traffic, whatever this traffic is intended for the MOPLL or for another slave on the bus. To avoid this I2C-bus crosstalk and be able to have a clean noise spectrum, it is necessary to use a bus gate that enables the signal on the bus to drive the MOPLL only when the communication is intended for the tuner part (such a kind of I2C-bus gate is included into the Philips terrestrial channel decoders), and to avoid unnecessary repeated sending of the same information. 8 I2C-BUS PROTOCOL
The TDA6650TT; TDA6651TT is controlled via the two-wire I2C-bus. For programming, there is one device address (7 bits) and the R/W bit for selecting read or write mode. To be able to have more than one MOPLL in an I2C-bus system, one of four possible addresses is selected depending on the voltage applied to address selection pin AS (see Table 5). The TDA6650TT; TDA6651TT fulfils the fast mode I2C-bus, according to the Philips I2C-bus specification (see Chapter 20), except for the timing as described in Fig.4. The I2C-bus interface is designed in such a way that the pins SCL and SDA can be connected to 5, 3.3 or to 2.5 V pulled-up I2C-bus lines, depending on the voltage applied to pin BVS (see Table 2).
The I2C-bus lines SCL and SDA can be connected to an I2C-bus system tied to 2.5, 3.3 or 5 V. The choice of the bus input threshold voltages is made with pin BVS that can be left open-circuit, connected to the supply voltage or to ground (see Table 2).

8.1 Write mode; R/W = 0
TDA6650TT; TDA6651TT
After the address transmission (first byte), data bytes can be sent to the device (see Table 3). Five data bytes are needed to fully program the TDA6650TT; TDA6651TT. The I2C-bus transceiver has an auto-increment facility that permits programming the device within one single transmission (address + 5 data bytes). The TDA6650TT; TDA6651TT can also be partly programmed on the condition that the first data byte following the address is byte 2 (divider byte 1) or byte 4 (control byte 1). The first bit of the first data byte transmitted indicates whether byte 2 (first bit = 0) or byte 4 (first bit = 1) will follow. Until an I2C-bus STOP condition is
sent by the controller, additional data bytes can be entered without the need to re-address the device. The fractional calculator is updated only at the end of the transmission (STOP condition). Each control byte is loaded after the 8th clock pulse of the corresponding control byte. Main divider data are valid only if no new I2C-bus transmission is started (START condition) during the computation period of 50 s. Both DB1 and DB2 need to be sent to change the main divider ratio. If the value of the ratio selection bits R2, R1 and R0 are changed, the bytes DB1 and DB2 have to be sent in the same transmission.

8.1.2 XTOUT OUTPUT BUFFER AND MODE SETTING
TDA6650TT; TDA6651TT
The crystal frequency can be sent to pin XTOUT and used in the application, for example to drive the clock input of a digital demodulator, saving a quartz crystal in the bill of material. To output fxtal, it is necessary to set T[2:0] to 001. If the output signal on this pin is not used, it is Table 6 T2 0 0 0 0 1 1 1 1 Notes XTOUT buffer status and test modes T1 0 0 1 1 0 0 1 1 T0 0 1 0 1 0 1 0 1
recommended to disable it, by setting T[2:0] to 000. This pin is also used to output 1/2fdiv and fcomp in a test mode. At Power-on, the XTOUT output buffer is set to on, supplying the fxtal signal. The relation between the signal on pin XTOUT and the setting of theT[2:0] bits is given in Table 6.

1. Automatic Loop Bandwidth Control (ALBC) is disabled at Power-on reset. After Power-on reset this feature is enabled by setting T[2:0] = 011. To disable again the ALBC, set T[2:0] = 011 again. This test mode acts like a toggle switch, which means each time it is set the status of the ALBC changes. To toggle the ALBC, two consecutive Control byte 1s (CB1), should be sent: one byte with T[2:0] = 011 indicating that ALBC will be switched on or off and one byte programming the test mode to be selected (see Table 23, example of I2C-bus sequence). 2. This is the default mode at Power-on reset. This mode disables the tuning voltage. 8.1.3 STEP FREQUENCY SETTING
The step frequency is set by three bits, giving five steps to cope with different application requirements. The reference divider ratio is automatically set depending on bits R2, R1 and R0. The phase detector works at either 4, 2 or 1 MHz. Table 7 shows the step frequencies and corresponding reference divider ratios. When the value of bits R2, R1 and R0 are changed, it is necessary to re-send the data bytes DB1 and DB2.

AUTOMATIC LOOP BANDWIDTH CONTROL (ALBC)
In a PLL controlled VCO in which the PLL reduces phase noise close to the carrier, there is an optimum loop bandwidth corresponding to the minimum integrated phase jitter. This loop bandwidth depends on different parameters like the VCO slope, the loop filter components, the dividing ratio and the gain of the phase detector and charge pump. In order to reach the best phase noise performance it is necessary, especially in a wide band system like a digital 2004 Mar 22 12
tuner, to set the charge pump current to different values depending on the band and frequency used. This is to cope with the variations of the different parameters that set the bandwidth. The selection can be done in the application and requires for each frequency to program not only the divider ratios, but also the band and the best charge pump current. The TDA6650TT; TDA6651TT includes the ALBC feature that automatically sets the band and the charge pump current, provided the IC is used in the DVB-T standard

TDA6650TT; TDA6651TT
Data can be read from the device by setting the R/W bit to 1 (see Table 12). After the device address has been recognized, the device generates an acknowledge pulse and the first data byte (status byte) is transferred on the SDA line (MSB first). Data is valid on the SDA line during a HIGH level of the SCL clock signal. Table 12 I2C-bus read data format
A second data byte can be read from the device if the microcontroller generates an acknowledge on the SDA line (master acknowledge). End of transmission will occur if no master acknowledge occurs. The device will then release the data line to allow the microcontroller to generate a STOP condition.

1. Accuracy is 0.03VCC. Bit BS5 must be set to logic 0 to disable the BS5 output port. The BS5 output port uses the same pin as the ADC and can not be used when the ADC is in use. 8.3 Status at Power-on reset
At power on or when the supply voltage drops below approximately 2.85 V (at Tamb = 25 C), internal registers are set according to Table 15. At power on, the charge pump current is set to 580 A, the test bits T[2:0] are set to 110 which means that the charge pump is sinking current, the tuning voltage output is disabled and the ALBC function is disabled. The XTOUT buffer is on, driving the 4 MHz signal from the crystal oscillator and all the ports are off. As a consequence, the high band is selected by default.

1. Maximum ratings cannot be exceeded, not even momentarily without causing irreversible IC damage. Maximum ratings cannot be accumulated. 2. The maximum allowed ambient temperature Tamb(max) depends on the assembly conditions of the package and especially on the design of the PCB. The application mounting must be done in such a way that the maximum junction temperature Tj is never exceeded. An estimation of the junction temperature can be obtained through measurement of the temperature of the top centre of the package (Tpackage). The temperature difference junction to case (Tj-c) is estimated at about 13 C on the demoboard (PCB 827-3). The junction temperature is: Tj = Tpackage + Tj-c 10 HANDLING Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be completely safe, it is desirable to take normal precautions appropriate to handling integrated circuits.

2. These values are given for information only. The thermal resistance depends strongly on the nature and design of the PCB used in the application.The thermal resistance given corresponds to the value that can be measured on a multilayer PCB (4 layers) as defined by JEDEC standard. 3. The junction temperature influences strongly the reliability of an IC. The PCB used in the application contributes in a large part to the overall thermal characteristic. It must therefore be insured that the junction temperature of the IC never exceeds Tj(max) = 150 C at the maximum ambient temperature. 12 CHARACTERISTICS VCCA = VCCD = 5 V, Tamb = 25 C; values are given for an asymmetrical IF output loaded with a 75 load or with a symmetrical IF output loaded with 1.25 k; positive currents are entering the IC and negative currents are going out of the IC; the performances of the circuits are measured in the measurement circuits Figs 27 and 28 for digital application or in the measurement circuits Figs 29 and 30 for hybrid application; unless otherwise specified.

Notes
TDA6650TT; TDA6651TT
1. Important recommendation: to obtain the performances mentioned in this specification, the serial resistance of the crystal used with this oscillator must never exceed 120 . The crystal oscillator is guaranteed to operate for any supply voltage between 4.5 V and 5.5 V and at any temperature between -20 C and +85 C 2. The drive level is expected with a 50 series resistance of the crystal at series resonance. The drive level will be different with other series resistance values. 3. The VXTOUT level is measured when the pin XTOUT is loaded with 5 k in parallel with 10 pF. 4. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency (IF). 5. The 1% cross modulation performance is measured with AGC detector turned off (AGC bits set to 110). 6. Channel SO2 beat is the interfering product of fRFpix, fIF and fosc of channel SO2; fbeat = 37.35 MHz. The possible mechanisms are: fosc - 2 x fIFpix or 2 x fRFpix - fosc. 7. The IF output signal stays stable within the range of the step frequency for any RF input level up to 120 dBV. 8. (N + 5) - 1 MHz pulling is the input level of channel N + 5, at frequency 1 MHz lower, causing 100 kHz FM sidebands 30 dB below the wanted carrier. 9. Limits are related to the tank circuits used in Figs 27 and 28 for digital application or Figs 29 and 30 for hybrid application. Frequency bands may be adjusted by the choice of external components. 10. The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from VCC = 5 to 4.5 V or from VCC = 5 to 5.25 V. The oscillator is free running during this measurement. 11. The frequency drift is defined as a change in oscillator frequency when the ambient temperature varies from Tamb = 25 to 50 C or from Tamb = 25 to 0 C. The oscillator is free running during this measurement. 12. The supply ripple susceptibility is measured in the measurement circuit according to Figs 27, 28, 29 and 30 using a spectrum analyser connected to the IF output. An unmodulated RF signal is applied to the test board RF input. A sinewave signal with a frequency of 500 kHz is superimposed onto the supply voltage. The amplitude of this ripple signal is adjusted to bring the 500 kHz sidebands around the IF carrier to a level of -53.5 dB with respect to the carrier. 13. This is the level of divider interferences close to the IF frequency. For example channel S3: fosc = 158.15 MHz, 1 f 4 osc = 39.5375 MHz. The low and mid band inputs must be left open (i.e. not connected to any load or cable); the high band inputs are connected to an hybrid. 14. Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator. 15. The step frequency rejection is the level of step frequency sidebands (e.g. 166.67 kHz) related to the carrier. 16. This is the level of the 9th and 11th harmonics of the 4 MHz crystal oscillator into the IF output.

The TDA6650TT, TDA6651TT PLL loop stability is guaranteed in the configuration of Figs. 27, 28, 29 and 30. In this configuration, the external supply source is 30 V minimum, the pull-up resistor R19, is 15 k and all of the local oscillators are aligned to operate at a maximum tuning voltage of 26 V. If the configuration is changed, there might be an impact on the loop stability. For any other configurations, a stability analysis must be performed. The conventional PLL AC model (cf. SIMPATA Philips software) used for the stability analysis, is valid provided the external source (DC supply source or DC-to-DC converter) is able to deliver a minimum current that is equal to the charge pump current in use. The delivered current can be simply calculated with the following formula: V DC - V T I delivered = ----------------------- > I CP R pu - Where Idelivered is the delivered current
TDA6650TT; TDA6651TT
VDC is the supply source voltage or DC-to-DC converter output voltage VT is the tuning voltage Rpu is the pull-up resistor between the DC supply source (or the DC-to-DC converter output) and the tuning line (R19 in Figs. 27 to 30) ICP is the charge pump current in use.

14 APPLICATION AND TEST INFORMATION 14.1 Tuning amplifier
TDA6650TT; TDA6651TT
The tuning amplifier is capable of driving the varicap voltage without an external transistor. The tuning voltage output must be connected to an external load of 15 k which is connected to the tuning voltage supply rail. The loop filter design depends on the oscillator characteristics and the selected reference frequency as well as the required PLL loop bandwidth. Applications with the TDA6650TT; TDA6651TT have a large loop bandwidth, in the order of a few tens of kHz. The calculation of the loop filter elements has to be done for each application, it depends on the reference frequency and charge pump current. A simulation of the loop can easily be done using the SIMPATA software from Philips. 14.2 Crystal oscillator
Do not use the signal on pins XTAL1 or XTAL2, or the signal present on the crystal, to drive an external IC or for any other use as this may dramatically degrade the phase noise performance of the TDA6650TT; TDA6651TT. 14.3 Examples of I2C-bus program sequences
Tables 16 to 23 show various sequences where: S = START A = acknowledge P = STOP. The following conditions apply: LO frequency is 800 MHz fcomp = 166.666 kHz N = 4800 BS3 output port is on and all other ports are off: thus the high band is selected Charge pump current ICP = 280 A Normal mode, with XTOUT buffer on IAGC = 220 nA AGC take-over point is set to 112 dBV (p-p) Address selection is adjusted to make address C2 valid. To fully program the device, either sequence of Table 16 or 17 can be used, while other arrangements of the bytes are also possible.
The TDA6650TT; TDA6651TT needs to be used with a 4 MHz crystal in series with a capacitor with a typical value of 18 pF, connected between pin XTAL1 and pin XTAL2. Philips crystal 4322 143 04093 is recommended. When choosing a crystal, take care to select a crystal able to withstand the drive level of the TDA6650TT; TDA6651TT without suffering from accelerated ageing. For optimum performances, it is highly recommended to connect the 4 MHz crystal without any serial resistance. The crystal oscillator of the TDA6650TT; TDA6651TT should not be driven (forced) from an external signal.

16 SOLDERING 16.1 Introduction to soldering surface mount packages
TDA6650TT; TDA6651TT
To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb or Pb-free respectively. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 16.4 Manual soldering
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. 16.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 270 C depending on solder paste material. The top-surface temperature of the packages should preferably be kept: * below 225 C (SnPb process) or below 245 C (Pb-free process) - for all BGA, HTSSON-T and SSOP-T packages - for packages with a thickness 2.5 mm - for packages with a thickness < 2.5 mm and a volume 350 mm3 so called thick/large packages. * below 240 C (SnPb process) or below 260 C (Pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. 16.3 Wave soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems.

1. For more detailed information on the BGA packages refer to the "(LF)BGA Application Note" (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 C 10 C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible. 4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 6. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request. 9. Hot bar or manual soldering is suitable for PMFP packages.
