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.
