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 PI3DBV40 is a 8- to 4-channel multiplexer/demultiplexer.
Industry leading advantages include 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 corresponding outputs or switches 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.
Applications
