I2C BUS-controlled, Wide-band with 50MHz Frequency
I2C BUS-Controlled Video Switching IC
MM3151
Announced on January 27, 2006
MM3151
§ Overview
This product employs Pure-CMOS process for the first time as a video switch, to add power-saving function, and thus realizes lowered power consumption.
This product also includes a filter which eliminates sampling noise at DAC when wide band component signal (D3, D4) are passing, and therefore enables the specification for select filtering (for D1~D4).

§ Features
1.
Component signal can be switched among 3 inputs (frequency characteristics: 50MHz)
2.
S video signal can be switched among 4 inputs, and composite signal can be switched among 6 inputs.
3.
3 lines of D/S terminal recognition systems are included.
4.
LPF cut off can be selected from 3 frequencies.
(fBW=6.75MHz, 13.75MHz, 27MHz)
5.
With 2 power sources of 9V and 5V for VDD, power saving is achieved.
6.
Supports Europe's skirt terminals.
