Description

Pericom Semiconductor’s PI3DBV series of logic circuits are

produced using the Company’s advanced sub-micron CMOS

technology, achieving industry leading performance.

The PI3DBV20 is a 4- to 2-Channel multiplexer/demultiplexer

Video Switch with Hi-Z outputs. Industry leading advantages in-

clude a propagation delay of less than 250ps, resulting from its low

channel resistance and I/O capacitance. The device multiplexes

differential outputs from a video source to one of two correspond-

ing outputs, or switch two inputs to a common display. The switch

is bidirectional and offers little or no attenuation of the high-speed

signals at the outputs. It is designed for low bit-to-bit skew, high

channel-to-channel noise isolation and is compatible with various

standards, such as LVDS and TMDS.
