PI3V512 Low On-Resistance, 3.3V Wideband/Video Switch 5-Port, 2:1 Mux/DeMux Features 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. RON is 4Ω typical Low bit-to-bit skew: 200ps Low crosstalk: –65dB @ 10MHz Low Current Consumption: 20µA Near-Zero propagation delay: 250ps Switching speed: 9ns Channel On-Capacitance: 6pF (typical) VCC Operating Range: +3.0V to +3.6V ESD>2000V . . . Human Body Model High Signal Passing bandwidth (600 MHz) Packaging (Pb-free & Green available): 24-pin QSOP (Q) 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.

The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.
