digital home freescale semiconductor 3 MC44CC375AV functional overview figure 2 shows a simplified block diagram of the MC44CC375AV device. there are two main sections: 1. a pll section to synthesize the vhf output channel frequency for channel 3 or channel 4. 2. a modulator section which accepts audio and video inputs and modulates the vhf carrier. the high frequency cmos technology allows integration of the uhf tank circuit and certain filtering functions eliminat- ing the need for a number of external components. figure 2. MC44CC375AV simp lified block diagram power supply do not bias any other pin before v cc is applied to the de- vice. standby modes during standby mode, the modulator is switched to low power consumption. the sound oscillator, uhf oscillator and vhf dividers, video and sound mo dulator sections bias are internally turned off. the modulator is programmed in standby mode when pin 16, psave , is set to a ?lo? level transient output inhibit to minimize the risk of interfer ence to other channels while the uhf pll is acquiring a lock on the desired frequency, the sound and video modulators are turned off at power-on (i.e., v cc is switched from 0 v to 3.3 v). there is a time-out of 263 ms until the output is enabled. this allows the uhf pll to settle to its programmed frequen- cy. during the 263 ms time-out, the sound pll current source is set to 10 a typical to speed up the locking time. after the 263 ms time-out, the current so urce is switched to 1.0 a. use care when selecting loop filter components to ensure the loop transient does not exceed this delay. internal control bus 3 12 11 8 7 5 6 9 14 16 1 2 4 10 13 15 clamp sound pfd program divider audio amplifier lpf alc peak white fm 31.25 khz 31.25 khz uhf osc (2 x f o ) prescaler 8 ref divider 128 vhf dividers program divider n11:n0 phase comp. xco sound oscillator and fm modulator gnd modulator section vco and pll section aux v cc audio preem video splflt v cc rfout soc psave chs gnd pllflt xtal (4 mhz) no connect xo prescaler 2 control section video modulator rf sound modulator
digital home 4 freescale semiconductor MC44CC375AV video section the modulator requires a composite video input with neg- ative going sync pulses and a nominal level of 1.0 v (pp) . this signal is ac coupled to the video input where the sync tip lev- el is clamped. the video modulation depth typical value is given for 1.0 v cbvs input level. it can be reduced by simply adding a resistive divider at video input, resulting in a lower signal seen by the video input stage. the video signal is then passed to a peak white clip circuit whose function is to soft clip the top of the video waveform if the amplitude from the sync tip to peak white goes too high. in this way, over-modulation of the carrier by the video is avoided. the clipping function is always engaged. the clipping happens at 106ire with 1.0 v pp video signal (100ire = 0.7 v pp video blank to white). sound section the pll multivibrator oscill ator is fully integrated. the sound modulator system cons ists 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 pre-emphasis circuit is a high-pass filter with an external capacitor c1 and an internal resistor (100 k ? typi- cal). the recommended capacitor value (750 pf) is for ntsc standards, time constant is 75 s. the audio bandwidth specification is for 50 hz to 15 khz range, with pre-emphasis circuit engaged. without this pre- emphasis circuit, it is possible to extend the audio bandwidth to high frequencies, as there is no internal frequency limita- tion (stereo application, sap, etc.). pll section ? dividers the reference divider is a fixed 128 resulting in a refer- ence frequency of 31.25 khz with a 4.0 mhz crystal. the 31.25 khz reference frequency is used for both the uhf and sound plls. the prescaler is a fixed 8 and is permanently engaged. the vhf divider is also a fixed 8. the programmable divider?s division ratio is controlled by the chs pin voltage in order to select channel 3 or channel 4. pin selection pins chs and psave are internally pulled up to 3.3 v, soc is internally pulled up by 1.8 v. by default (open condi- tion), all pins are ?hi?. table 2. configuration pin settings pin no pin name lo (grounded) hi* 1 chs ch3 - 61.25 mhz ch4 - 67.25 mhz 3 soc sound on sound off 16 psave power save mode normal mode *please do not pull pin 3 to high vo ltage. for hi condition, leave pin 3 open.

digital home freescale semiconductor 11 MC44CC375AV audio modulation index ? fm modulation video: black sync audio signal: 1.0 khz, 205 mvrms. this is measured using a demodulator and an audio analyzer at 1.0 khz. the audio signal 205 mv at 1.0 khz 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 video: black sync audio signal: 50 hz to 15 khz, 100 mv rms this is measured using a demodulator and an audio analyzer. the audio signal 1.0 khz 100 mv rms 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 (0 db). the audio signal is then swept from 50 hz to 15 khz, and demodulated ac amplitude is measured in db rela tive to the 1.0 khz reference. audio pre-emphasis and de-emphasis circuits are engaged, all audio analyzer filters are switched off. audio distortion fm audio: 1.0 khz, adjustable level video: black sync this is measured using a demodulator and an audio analyzer at 1.0 khz. the output level of the audio analyzer is varied to obtain a deviation of 25 khz indicated on the demodulator. the input rms detector of the audio analyzer converts the ac level of the combined signal + noise + distortion to dc. it then removes the fundamental signal (1.0 khz) 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. audio signal to noise audio: 1.0 khz, adjustable level video: ebu color bars this is measured using a demodulator and an audio analyzer at 1.0 khz. the output level of the audio analyzer is varied to obtain a modulation deviation of 25 khz indicated on the amfs demodulator. the audio analyzer alternately turns on and off its 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 inte rnal ccir468-2 filter of the audio analyzer together with the internal 30 2.0 khz (60 db/decade) lowpass filters. the amfs demodulator uses a quasi-para llel 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 in tercarrier conversion. in this mode the phase noise information fully cancels out and the true s/n can be measured. table 9. performance measurement test set-ups (continued) device and signals set-up measurement set-up adist distorsion noise + () distorsion noise signal ++ () ? = asn db () 20 signal noise + () noise () ? log =
