MOTOROLA SEMICONDUCTOR----- TECHNICAL DATA Product Preview Advanced Multistandard TV Video/Sound IF The MC44302 is a new multistandard single channel TV Video/Sound IF and PLL detector system for all standard transmission systems. This device enables the designer to produce a high quality IF system with white spot inversion, AFT and AGC. The MC44302 was designed with an emphasis on linearity to minimize sound/picture intermodulation. Features: • Single Coil Adjustment for AFT and PLL • VCO at 112 IF for Minimum Beats • Simple Circuitry for Low System Cost • White Spot Inversion • Symmetrical ± 2.0 MHz Pull-In • User Selectable Positive or Negative Modulation • Simple Alignment Procedure • AGC Gating Input Options Sound Features: • Self-Tuning, Low Distortion FM IF Demodulator • AM Sound IF for SECAM • Sound Muting • Variable and Constant Audio Outputs Added Features Will Include: • FM IF Demodulator • AM Sound IF for SECAM • AGC Gating Input Options • Mode Select Pin for Selecting M, B-G-I, Lor D2MAC • Sound Muting PRODUCT DESCRIPTION Advanced TV Video/Sound IF for PAL, NTSC, SECAM and AM D2MAC MC44302 ADVANCED MULTISTANDARD TV VIDEO/SOUND IF SILICON MONOLITHIC INTEGRATED CIRCUIT PSUFFIX PLASTIC PACKAGE CASE 710 DWSUFFIX PLASTIC PACKAGE CASE 751F (SO·2BL) ORDERING INFORMATION Temperature Device Range Package MC44302DW SO-2BL A' to + 70°C MC44302P Plastic DIP The MC44302 is a new multistandard TV Video/Sound IF SECAM (system L), NTSC (system M), and AM D2MAC. that will have the present MC44301 as its basis. All present Added features include self-contained AGC systems, AM and features and performance (with the exception of the AM FM demodulation, volume control, and circuitry designed to detector) will be retained. meet Peri-TV socket requirements. PAL, NTSC and SECAM The circuit will demodulate the sound and video of all of the are selected via Pin 11 (voltage level) and AM D2MAC by world's major television systems, namely PAL (system B, G, I), grounding Pin 16 (normally used as a PLL filter).

Modes PAL - In the PAL mode the AGC is self-gating via a horizontal PLL which is locked to the video. The gating pulse samples the video level during the sync interval. FM sound demodulation is active in the PAL mode. The FM demodulator is self-tuning over the range of 5.5 MHz to 6.0 MHz. Other frequencies can be chosen by externally switching a capacitor on Pin 3. The FM demodulator has low distortion (approximately 0.1 %) with better than 70 dB signal to noise ratio. Two sound modes are possible in PAL; with and without sound muting. The sound output also has constant and variable audio outputs which meet the requirements of the European Peri-TV socket. External audio can be switched through to the variable output via Pin 3. The internal variable signal is inhibited, but the internal constant audio still appears at Pin 24. This means that the external audio signal can be used internal to the TV chassis and its level adjusted via the volume control (Pin 1), while the internal audio can be taken from the constant output (Pin 24) via the Peri-TV socket to some external device such as a VCR. SECAM - An advanced form of back porch gated AGC is used in SECAM mode. A long term peak white detector also controls the video output level over a limited range, correcting for any errors in the transmitted black level. In this way the AGC system retains the accuracy of a peak detecting system IF I Input L AGC Riter RF AGC Gnd Mode VCC SW Flyback/ Video Filter Input DMAC Select MC44302 Simplified Block Diagram AFT AFT SW Lock without the usual sacrifice of speed. The peak white detector uses the FM AFT filter capacitor at Pin 7. Thus the need for an extra pin and capacitor for this function is avoided. The video switches maintain the same video sense as in PAL at the video outputs. The FM demodulator circuitry is disabled and the AM demodulator is switched on. All other aspects of the sound system are similar to PAL with regards to the audio switching. NTSC - The AGC system is the same for NTSC as in PAL mode. Both FM and AM demodulators are active when NTSC mode is activated. The demodulator FM is routed to the variable audio output to be used as the TV chassis drive for the loudspeaker. At the same time, the AM output is fed to the constant output. This can be used for suppressed sync scrambling systems, where the sync is on the sound carrier, to recover the sync signal. Grounding Pin 3 when in the NTSC mode inverts the output video polarities. This is useful in scrambling systems that invert the video from line to line. AM D2MAC - In this mode, the AGC system is a simple, very long time constant peak detector. The FM AFT filter capacitor at Pin 7 is used for this time constant. Both the FM and AM sound demodulators are switched off. This is to prevent interference with the D2MAC digital sound in the sync system.
