2 MC44BC375UA technical data motorola features 1 features channels are selectable using pin channel selection (chs) and tuned by a pll. they do not require any external tank circuit components thus reducing the sensitivity of the pcb design and the need for external adjustments. the pll obtains its reference from a 4mhz crystal oscillator. the sound subcarrier is also generated on-chip without external components. the 4.5mhz or 5.5mhz sound frequency is selectable via pin sound frequency selection (sfs). the picture to sound subcarrier ratio is also selectable by pin picture to sound selection (pss) to either 14db or 16db. a power save function is selectable via pin psave/lo which turns off all internal vcos and mixers and simultaneously switches on the logic output port (lop). no external varicap diodes/ inductor nor other tuned components are needed. the MC44BC375UA also has the following features. ? channel selected by chs pin integrated on-chip oscillator - no external tank circuit extremely low external components count adjustable video modulation depth (85% w/o adjustment) peakwhiteclip programmable picture/sound carrier ratio (14db & 16db) selected by pss pin integratedon- c hip programmable sound subcarrier oscillator (4.5 & 5.5mhz selected by sfs pin) no external varicaps modulator standby mode selected by psave/lo pin transient output inhibit during pll lock-up at power-on logic output port selected by psave/lo pin (antenna switch driver) extremely robust esd protection, minimum 4kv, typical) 6kv. available in 76 db v rf output level (mc44bc375u)

12 MC44BC375UA technical data motorola modulator functionality 12 modulator functionality 12.1 power supply the two device vccs (pins 11 and 14) 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 device. 12.2 test modes the MC44BC375UA test modes are enabled by any voltage level higher than vcc on pins chs, pss, sfs and video. care must be taken in the application to not reach levels higher than vcc on those pins. 12.3 standby modes during standby mode, the modulator is switched to low power consumption: the sound oscillator, uhf oscillator and vhf dividers, video and sound modulator sections bias are internally turned off. modulator is programmed in standby mode when pin 9 psave/lo is set to ?lo? level (see pin selection section). 12.4 logic output port the logic output port is used to control an external switch (such as an antenna switch or an attenuator). this pin is an open collector transistor able to drive up to 15ma at low voltage. lop level is switched between ?hi? and ?lo? level with pin 9 ?psave/lo? (see pin selection section). 12.5 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 at power-on from zero (i.e. vcc is switched from 0v to 5v or device is switched from ?standby mode? to ?normal operation?). 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. for test purposes, it is possible to disable the 263ms delay (see test modes section). 12.6 video section the modulator requires a composite video input with negative going sync pulses and a nominal level of 1vp-p. this signal is ac coupled to the video input where the sync tip level is clamped. video modulation depth typical value is given for 1v cbvs input level. it can be adjusted to any lower value by simply adding a resistive divider at video input, resulting in a lower signal seen by the video input stage.
modulator functionality motorola MC44BC375UA technical data 13 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. 12.7 sound section the multivibrator oscillator is fully integrated and does not require any external component. an internal low pass filter and matched structure give very low harmonics level. 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 pre-emphasis circuit is a high-pass filter with an external capacitor c1 and an internal resistor (100kohms typical). the recommended capacitor value (750pf) is for m/n standards; time constant is 75 s. it is 470pf for b/g standards (50 s). audio bandwidth specification is for 50hz to 15khz range, with pre-emphasis circuit engaged. without this pre-emphasis circuit, it is possible to extend the audio bandwidth to the high frequencies as there is no internal frequency limitation (stereo application). 12.8 pll section ? dividers the reference divider is a fixed divide by 128 resulting in a reference frequency of 31.25khz with a 4.0mhz crystal. the 31.25khz reference frequency is used for both uhf and sound plls. the prescaler is a fixed divide by 8 and is permanently engaged. the vhf divider is also a fixed divide by 8. the programmable divider?s division ratio is controlled by chs pin voltage in order to get the channel 3 or channel 4. 12.9 selectable pins pins chs, pss, sfs are internally pulled up to 5v.
