Monolithic IC MM1166

Outline

This is a superimpose IC that supports S-VHS, with 1 circuit for Y signals and 1 circuit for C signals, with
built-in character level and border level. The level is suppressed to eliminate the problem of spike noise
generated when switching between input video signal and character signal.

Features

1. Supports S-VHS

2. Built-in character and border levels

3. Frequency response Y : 10MHz C : 5MHz

4. Input/output signal 1V

P-P

5. Operating power supply voltage range 4.5~5.5V

Package

SOP-8C (MM1166XF)

Applications

1. TV

2. VCR

3. VCR with camera
