PI5V512
Low On-Resistance, 5V Wide-Bandwidth
5-port, 2:1 Mux/DeMux VideoSwitch
Description
Pericom Semiconductor’s PI5V512 is a true bidirectional 5-Port 2:1
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
be switched in addition to switching the RGB and composite signals
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.
