General Description
The BCT4222B is a high bandwidth, fast double-pole
double-throw (DPDT) analog switch. Its wide
bandwidth and low bit-to-bit skew allow it to pass
high-speed differential signals with good signal
integrity. Each switch is bidirectional and offers little or
no attenuation of the high-speed signals at the outputs.
Industry-leading advantages include a propagation
delay of less than 250ps, resulting from its low channel
resistance and low I/O capacitance. Its high
channel-to-channel crosstalk rejection results in
minimal noise interference.
