Description
Pericom Semiconductor’s PI3V512 is a true bi-directional 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 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.
Industry leading advantages include a propagation delay of less than
250ps, resulting from its low channel resistance and I/O capacitance.
The switch is bi-directional and offers little or no attenuation of the
high-speed signals at the outputs. The device also has exceptional
high current capability which is far greater than most analog switches
offered today. The PI3V512 offers a high-performance (600 MHz),
low-cost solution to switch between video sources.
Applications
• Projection TV and LCD TV
• Video consumer applications
• Analog video signal processing
