HD3SS460EVM-SRC
The HD3SS460 is a high-speed passive crosspoint switch designed to support low- and high-speed signal
switching required for Type C, with Alternate mode applications. This guide describes how to bring up the
EVM and includes schematics that can be used as reference design for the Alternate mode
implementations of the host systems with the HD3SS460 device.
