Evaluation board

TMUXHS221EVM — TMUXHS221 2-channel differential 2:1/1:2 high-speed mux/demux switch evaluation module

The TMUXHS221 evaluation module (EVM) can be used to evaluate many high-speed interfaces for data rates up to 3 Gbps, such as USB 2.0 and eUSB2 LS, FS, and HS signal. This EVM can also be used as a hardware reference design for implementations of the TMUXHS221.
