Outline

This IC is a video switch IC developed for high-end large/medium TVs incorporating three 3-input 2-output circuits. It is ideal for switching BS/JSB/CS or M-N converters (mute to NTSC conversion). The BS-CS decoder can be used as a W decoder.

Features

1. One of the two video signal outputs is used for external output, and has a 6dB amp, 75Ω, 1VP-P

2. Input impedance

1~3 video circuits 15kΩ

1~3 audio circuits 68kΩ

3. Crosstalk

Video -60dB (at 4.43MHz)

Audio -80dB (at 1kHz)

Video : Audio -70dB (at 100kHz)

4. Frequency response 10MHz (6dB, 75Ω, amp only, 7MHz)

5. Supply voltage 8.0~13.0V

Applications

1. TV

2. Free-standing VCR

3. Other video equipment
