PI3DBV20
3.3V, Wide Bandwidth, 2-Channel,
2:1 Mux/DeMux Video Switch w/ Single Enable
Features
Description
• R is 4Ω typical
Pericom Semiconductor’s PI3DBV series of logic circuits are
produced using the Company’s advanced sub-micron CMOS
technology, achieving industry leading performance.
ON
• Low bit-to-bit skew: 200ps
• Low-Crosstalk: –27dB @ 250MHz
• Near-Zero propagation delay: 250ps
• Switching speed: 9ns
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.
• Channel On-Capacitance: 9pF (typical)
• V Operating Range: +3.0V to +3.6V
