PI5V512 Low On-Resistance, 5V Wide-Bandwidth 5-port, 2:1 Mux/DeMux VideoSwitch Features * High-performance, low-cost solution to switch between video sources * Wide bandwidth: 550 MHz * Low On-Resistance: 5 * Low crosstalk at 10 MHz: -90dB * Ultra-low quiescent power (0.1A typical) * Single supply operation: +5.0V * Fast switching: 10ns * Packaging (Pb-free & Green available): - 24-pin 150-mil wide plastic QSOP (Q) 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 bidirectional 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.
