The TMUXHS5212 is a 2-channel bidirectional passive switch with 2:1 mux or 1:2 demux configurations. It supports differential signaling up to 32Gbps NRZ, thus enabling it for many applications including PCI Express 5.0, USB 4.0, 50G Ethernet, CXL 3.1 and Thunderbolt™ 4. The device operates off of a 1.8V supply with ultra low active and standby power, and its control pins are compatible with 1.8V digital inputs.
The dynamic characteristics of the TMUXHS5212 allow for high-speed switching with minimal attenuation and negligible added jitter to the eye diagram for both NRZ and PAM applications. It is designed for best intra-pair skew performance, low crosstalk, and reliable signal integrity.
The TMUXHS5212 is rated for a temperature range of -40°C to 105°C that can suit commercial, industrial and personal electronics applications.
