I/O Interface

BH7625KS2

Description

BH7625KS2 is a video signal selector with two built-in sync separation circuits, and two sync detector circuits. It includes

5-composit, 5-Y, 5-C, and 1-component video signal inputs that can be selected freely for each output. Additionally, The

existance of the signal outputted from outside can be judged by only this chip.

Features

1) Built-in 5-video, 5-Y, 5-C and 1-component inputs

2) Input terminal of the S2 standard suitability

3) I²C-BUS control (High impedance when power supply off)

4) Built-in 0/3dB switch AMP㧔CVBS OUT, C OUT㧕

5) Built-in 0/6dB switch AMP㧔Y/CVBS OUT㧕

6) Built-in sync separation circuit㧔2 circuits SYNC OUT, V SYNC OUT㧕

7) Built-in sync detector circuit㧔2 circuits㧕

8) Built-in 3 LPF circuits㧔4 order + TRAP㧕
