TUSB1146-Q1 USB Type-C® Evaluation Module
Description
The TUSB1146-Q1 USB Type-C
redriving switch supports data rates up to 10Gbps for
a downstream facing port (host). The TUSB1146Q1-
EVM uses the TPS65987 PD controller for CC pin
control and to configure the device in pin-strap mode.
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 TUSB1146-Q1.
4. For issues, reach out to us directly on the TI E2E
forum.

1.4 Device Information The TUSB1146-Q1 is a VESA USB Type-C alt mode redriving switch supporting USB 3.1 data rates up to 10Gbps and DisplayPort 1.4 up to 8.1Gbps for a downstream facing port (source). The device is used for D_DFP pin assignments C, D, and E from the VESA DisplayPort alt mode on USB Type-C standard. - Page 3 Shunt on pin 3 - 4 (PD) 2.1.1 Power The TUSB1146-Q1 EVM is designed to draw power from the upstream USB connection. If DisplayPort-only operation is desired, a 5V power source must be attached to J1. 2.2 TUSB1146-Q1 Equalization Control Equalization (EQ) can be controlled using I C or pin-strapping.
- Page 4 3 Software 3.1 Firmware Description The TUSB1146-Q1 EVM uses the TPS65987 power delivery (PD) controller to manage the Type-C VBUS, handle configuration channel negotiation, and to set the CTL0/CTL1/FLIP pins on the TUSB1146-Q1. The TPS65987 can be configured by loading firmware through the SPI programming header located on the side of the EVM.
