Description

PericomSemiconductor’sPI5V512isatruebidirectional5-Port2:1

multiplexer/demultiplexer with Hi-Z outputs that is recommended

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 video switch 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 device also has exceptional high current capability which is

far greater than most analog switches offered today. A single 5V

supply is all that is required for operation. The switch is bidirec-

tional and offers little or no attenuation of the high-speed signals at

the outputs. The PI5V512 offers a high-performance (550 MHz),

low-cost solution to switch between video sources.
