EVM User's Guide: TUSB1046EVM
TUSB1046 USB Type-C™ Enabler
Description
The TUSB1046 USB Type-C
driving switch supports data rates up to 10Gbps
for a downstream facing port (host). This user's
guide describes how to use the EVM and includes
schematics that can be used as a reference design
for the alternate mode implementations of the host
system with the TUSB1046 device.
Get Started
1. Order the EVM
2. Configure the board headers to fit your application
3. Use the EVM and associated design files to
evaluate the TUSB1046
4. For issues, reach out to us directly on the TI E2E
