For More Information On This Product, Go to: www.freescale.com Features Freescale Semiconductor, Inc. 1 Features The MC44BS374T1/374T1A is a PAL/NTSC Modulator with integrated VCO. The channel is set by an on-chip high-speed I2C compatible bus receiver. A Phase-Locked Loop ( PLL ) tunes the modulator over the full UHF range. The modulator incorporates a sound subcarrier oscillator and uses a second PLL to derive 4.5, 5.5, 6.0, and 6.5 MHz subcarrier frequencies. These frequencies are selectable by bus. The picture-to-sound ratio may be adjusted using the bus. In addition, an on-chip video test pattern generator can be switched ON with a 1 KHz audio test signal. The MC44BS374T1/374T1A have the following features: * * * * * * * * * * * * * * * * * * * Integrated on-chip programmable UHF oscillator No external varicaps diodes / inductor or tuned components Extremely low external components count Channel 21-69 UHF operation VHF range possible by internal dividers (30MHz-450MHz) Boosted TV output level (82 dBuV typical) for the MC44BS374T1A TV output level of 75 dBuV typical for the MC44BS374T1 High speed read and write I2C-bus compatible (800kHz) I2C-bus 5V and 3.3V compatible Fixed video modulation depth (82% typical) Peak White Clip disabled by bus Programmable picture/sound carrier ratio (12 dB and 16 dB) Integrated on-chip programmable sound subcarrier oscillator (4.5, 5.5, 6.0 and 6.5 MHz) - No external varicaps On-chip video test pattern generator with sound test signal (1kHz) Low-power programmable modulator standby mode Transient output inhibit during PLL Lock-up at power-ON Logical Output Port controlled by bus Start-up on channel `71' (871.25 MHz) ESD protection, minimum 4 kV Freescale Semiconductor, Inc... 2 Comparing the MC44BS374T1 and MC44BS374T1A to the MC44BC374T1 Compared to the MC44BC374T1 devices, the MC44BS374T1/374T1A has the following improvements: * * * * Higher output level for the MC44BS374T1A (82 dBuV versus 74.5 dBuV) Higher Video signal to noise (+ 3 dB) for the MC44BS374T1A I2C-bus 3.3V compatible Lower power consumption in normal and standby modes (-2 mA) MC44BS374T1/374T1A Advance Information For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. * * * * * The device can be powered down without holding the I2C lines down Pin Descriptions Switch between the two integrated VCO's controlled directly by the frequency divider (@ 700 MHz) The external standby pin is no more required as the I2C lines are not hold down when the device is not powered up. The standby pin is replaced by the LOP Logic Ouput Port pin (pin 3) Lower RF second harmonic spurious but higher third harmonic spurious. In the application it is easier to filter UHF third harmonics spurious than second harmonics as these frequencies are always out of the UHF band. Unfortunately the second harmonic can fall back into the same UHF band (for instance channel 21 second harmonic). For this reason it is almost impossible to have a good rejection of low UHF second harmonic with an external low pass filter. This is the reason why the design has been optimized for a maximum second harmonic rejection in spite of an increase of the third harmonic. Freescale Semiconductor, Inc... 3 Pin Descriptions Table 1.

Measurement Conditions Device and Signals Set-up Video Bandwidth The Video signal is demodulated on the spectrum analyzer, and the peak level of the 100KHz signal is measured as a reference. The frequency is then swept from 100KHz to 5MHz, and then the difference in dB from the 100KHz reference level is measured.

Table 7. Measurement Conditions Device and Signals Set-up Measurement Set-up Audio Modulation Depth Video Black Level Audio signal: 1Khz, 205mVrms. This is measured using a Rohde & Schwarz AMFS Demodulator in B/G and a HP8903A Audio Analyzer at 1kHz The audio signal 205mV at 1kHz is supplied by the Audio Analyzer, and the FM demodulated signal deviation is indicated on the Demodulator in Khz peak. This value is then converted in% of FM deviation, based on specified standards. Audio Frequency response The audio signal 1KHz 100mVrms is supplied by the Audio Analyzer, demodulated by the Demodulator and the audio analyzer measures the AC amplitude of this demodulated audio signal: this value is taken as a reference (0dB). The audio signal is then swept from 50Hz to 15KHz, and demodulated AC amplitude is measured in dB relative to the 1KHz reference. Audio pre-emphasis and de-emphasis circuits are engaged, all audio analyzer filters are switched OFF. Audio Distortion FM Audio: 1Khz, adjustable level Video Black Level This is measured using a Rohde & Schwarz AMFS UHF Demodulator in B/G and a HP8903A Audio Analyzer at 1kHz. The output level of the Audio analyzer is varied to obtain a deviation of 50kHz indicated on the Demodulator. The input arms detector of the Audio Analyzer converts the ac level of the combined signal + noise + distortion to dc. It then removes the fundamental signal (1kHz) after having measured the frequency. The output rms detector converts the residual noise + distortion to dc. The dc voltmeter measures both dc signals and calculates the ratio in% of the two signals. ADist = ( Distorsion + Noise ) ( Distorsion + Noise + Signal ) Audio Signal to Noise The Audio Analyzer alternately turns ON and OFF it's internal audio source to make a measure of the Audio signal plus noise and then another measure of only the noise. The measurement is made using the internal CCIR468-2 Filter of the Audio Analyzer together with the internal 30+/-2kHz (60dB/decade) Lowpass filters. The AMFS demodulator uses a quasi-parallel demodulation as is the case in a normal TV set. In this mode the Nyquist filter is bypassed and the video carrier is used without added delay to effectuate intercarrier conversion. In this mode the phase noise information fully cancels out and the true S/N can be measured. ASN ( dB ) = 20 x log ( Signal + Noise ) ( Noise ) Freescale Semiconductor, Inc...

FL-Low Order Bits Note: Note: Note: Note: Note: N0 to N11 are set to have UHF oscillator on channel 71 ( 871.25 MHz ). Peak White Clip is ON. Sound frequency is 5.5 MHz. Logic Output Port is low voltage Picture to sound ratio is 12 dB. 16.2 Power Supply The three device Vccs (pins 10, 13 and 15) must be applied at the same time to ensure all internal blocks are correctly biased. Do not bias any other pin before Vcc is applied to the MC44BS374T1/374T1A. When all Vccs are switched to 0V, SDA and SCL pins are high impedance. 16.3 Standby modes During standby mode, the modulator is switched to low power consumption. That is, the sound oscillator, UHF oscillator, and the video and sound modulator section's bias are internally turned OFF. The I2C bus section remains active. The MC44BS374T1/374T1A can be set to standby mode with a combination of 3 bits: OSC=0, SO=1 and ATT=1 16.4 Transient Output Inhibit To minimize the risk of interference to other channels while the UHF PLL is acquiring a lock on the desired frequency, the Sound and Video modulators are turned OFF during a time out period for each of the following two cases: * * Power-ON from zero ( i.e., all Vcc is switched from 0 V to 5 V ). UHF oscillator power-ON from OFF state ( i.e., OSC bit is switched from 1 to 0 ) There is a time-out of 263ms until the output is enabled. This lets the UHF PLL settle to its programmed frequency. During the 263ms time-out, the sound PLL current source is set to 10 A typical to speed up the locking time. After the 263ms time-out, the current source is switched to 1 A. Use care when selecting loop filter components, to ensure the loop transient does not exceed this delay. MC44BS374T1/374T1A Advance Information For More Information On This Product, Go to: www.freescale.com Modes of Operation Freescale Semiconductor, Inc. For test purposes, it is possible to disable the 263ms delay using Test Mode 1-State 1.h (this is called speed up mode). 16.5 UHF Oscillator-VHF range The UHF oscillator is fully integrated and does not require any external components. For low frequency testing or VHF range operation ( test mode 1, states 1.b to 1.e ), the UHF oscillator can be internally divided by: 2, 4, 8, or 16. 16.6 UHF PLL Section The reference divider is a fixed divide-by-128, resulting in a reference frequency of 31.25 KHz with a 4.0 MHz crystal. Freescale Semiconductor, Inc... The prescaler is a fixed divide-by-8 and is permanently engaged. The programmable divider division-ratio is controlled by the state of control bits N0 to N11. The divider-ratio N for a desired frequency F (in MHz) is given by: F 128 N = -- x -------8 4 with: N = 2048 x N11 + 1024 x N10 + ...... + 4 x N2 + 2 x N1 + N0 NOTE: Programming a division-ratio N=0 is not allowed. 16.7 Logic Output Port (LOP) The LOP pin controls any logic function. The primary applications for the LOP are to control an external attenuator or an external switch, between the antenna input and TV output. A typical attenuator application with PIN diode is shown in Figure 7. The LOP pin switches the PIN attenuator depending on the signal strength of the Antenna Input. This reduces the risks of intermodulation in certain areas. The LOP can also be used as an OFF position bypass switch or for other logic functions in the application. Vcc Antenna Input TV Out LOP pin Figure 7. Typical Attenuator Application with Pin Diode MC44BS374T1/374T1A Advance Information For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. 16.8 Video Section - Peak White Clip The MC44BS374T1/374T1A requires the following for proper video functionality: * * A composite video input with negative going sync pulses A nominal level of 1 Vpp Modes of Operation This signal is AC-coupled to the video input where the sync tip level is clamped. The video signal is then passed to a Peak White Clip (PWC) circuit. The PWC circuit function soft-clips the top of the video waveform, if the sync tip amplitude to peak white clip goes too high. This avoids carrier over-modulation by the video. Clipping can be disabled by software. 16.9 Test Pattern Generator Freescale Semiconductor, Inc... The I2C generates a simple test pattern, which can be switched under bus control to permit a TV receiver to easily tune to the modulator output. The pattern consists of two white vertical bars on a black background and a 976 Hz audio test signal. TE2 7/10 3/10 TE1 0 10 20 24 2830 40 44 50 60 64 TIME IN S. Figure 8. Test Pattern Generator MC44BS374T1/374T1A Advance Information For More Information On This Product, Go to: www.freescale.com Modes of Operation Freescale Semiconductor, Inc. 16.10 Sound Section The oscillator is fully integrated and does not require any external components. An internal low-pass filter and matched structure provide very low harmonics levels. The sound modulator system consists of an FM modulator incorporating the sound subcarrier oscillator. The audio input signal is AC-coupled into the amplifier, which then drives the modulator. The audio preemphasis circuit is a high-pass filter with an external capacitor and an internal resistor ( 106 K Ohms typical ). The recommended capacitor value for BG standard (with a time constant of 50 S) is 470 pF. The recommended capacitor value for M/N standard (with a time constant of 75 S) is 750 pF. To increase the audio bandwidth at low frequencies it is possible to change the sound PLL loop filter. The recommended values are 220 nF and 22 nF. To increase the bandwidth at low frequencies (lower than 50 Hz) it is possible to use larger loop filter capacitor values. This will give a lower cut off frequency. In this case it is necessary to calculate the new values of the loop filter according to the required Q factor and loop bandwidth. This is described in the following figure: Freescale Semiconductor, Inc... Sound PLL loop filter calculation Loop filter equation : o = 1 Kpd * Kosc , Q= , with : N * C1 R * C1 * o o = 3dB cut off frequency Kpd = 1uA : Phase detector current Kosc = 5MHz/V : sound oscillator slope (in fact Kosc=40MHz/prescaler divider =8) This gives 5 MHz/V N = sound divider ratio Q = quality factor C2, added to minimize glitches, is usually set to one tenth the size of C1. Example : Fref=31.25KHz N=5.5MHz / 31.25KHz = 176 Assuming C1= 220 nF, then o = 360 rad, and fo= 57Hz Q depends on the desired frequency response ; Choosing Q = 0.7 as a starting point, then R= 18 k. The resistance acts directly on the factor quality and can be adjusted to create peaking on the low frequency range. It is recommended to adjust the value of R experimentally depending on the application and requirements. In the proposed application schematic a value of 15 k has been chosen. Figure 9.
