Overview

The LA7316A-N, 7316AM are VHS chroma signal processor ICs that have the following features.

1. Adjustment-free 3.58MHz VXO free-running OSC frequency, 160fH VCO free-running OSC frequency, carrier leak, PB chroma level, except REC chroma level.

2. The chip size is greatly reduced by using our most advanced process technology for fine structure. Since the LA7316A-N, AM are designed for NTSC system, the package can be made so small as the DIP-24S and a minimum number of external parts is required and it occupies much less space on the board, thereby facilitating VCR set design.

3. Multifunction 2fSC generator for CCD drive, PB chroma (629k) level compensation amplifier, function to select APC loop input signal passed/not passed through comb filter, BGP output, 3rd lock protector of 3.58MHz OSC.

4. LPF usable for REC/PB

5. Capable of being operated from 5V supply.

6. Current drain : 48mA at REC mode 50mA at PB mode
