Image and pinouts :
The OM8373 and OM8378 combine the functions of a video processor together with a µ-Controller and US Closed Caption decoder. The ICs are intended to be used
in economy television receivers with 110° picture tubes. The ICs have supply voltages of 8 V and 3.3 V and they are mounted in a SDIP-64 envelope.
• Vision IF circuit suitable for negative modulation with alignment-free PLL demodulator
• Internal (switchable) time-constant for the IF-AGC circuit
• The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz).
The quality of this system is such that the external band-pass filters can be omitted.
• Source selection between the ‘internal’ CVBS and an external CVBS or Y/C signal
• 1 external audio input.
• Integrated chrominance trap circuit
