TMUXHS4212IRKST

The TMUXHS4212 is a high-speed bidirectional
passive switch in mux or demux configurations. It is
suited for many applications including USB Type-C™
and PCI Express. The TMUXHS4212 is a generic
analog differential passive mux or demux that works
for many high-speed differential interfaces with data
rates up to 16 Gbps. The device can be used for
higher data rates where the electrical channel has
signal integrity margins. The TMUXHS4212 supports
differential signaling with common mode voltage
range (CMV) of up to 0 to 1.8 V and with differential
amplitude up to 1800 mVpp. Adaptive CMV tracking
ensures the channel through the device remains
unchanged for the entire common mode voltage
range.
The dynamic characteristics of the TMUXHS4212
allows high-speed switching, minimum attenuation to
the signal eye diagram, and with very little added
jitter. The device’s silicon design is optimized for
excellent frequency response at higher frequency
spectrum of the signals. Its silicon signal traces and
switch network are matched for best intra-pair skew
performance.
The TMUXHS4212 has an extended industrial
temperature range that suits many rugged
applications including industrial and high reliability use
cases.
