Description

Pericom Semiconductor’s PI3V512 is a true bi-directional 5-Port 2:

1multiplexer/demultiplexerwithHi-Zoutputsthatisrecommended

for both RGB and composite video switching applications.With the

additional 2 ports, vertical and horizontal synchronous signals can

beswitchedinadditiontoswitchingtheRGBandcompositesignals

between different components, such as DVD, VCR, PCs and etc.

The VideoSwitch can be driven from a current output RAMDAC

or voltage output composite video source.

Low On-Resistance, Low Crosstalk, Low OFF Isolation and wide

bandwidth features make it ideal for video and other applications.

The switch is bi-directional and offers little or no attenuation of the

high-speed signals at the outputs. The device also has exceptional

highcurrentcapabilitywhichisfargreaterthanmostanalogswitches

offered today. The PI3V512 offers a high-performance (600 MHz),

low-cost solution to switch between video sources.
