EVM Operation
Install the EVM using the following steps:
1. Attach a USB2 or USB3 cable from a host PC Type A connector to the Type B connector (P1) of the
TUSB213 EVM.
2. Attach a USB device either via cable or directly plugged into the Type A receptacle connector (P2) on
the TUSB213 EVM.

USB 2.0 High-Speed Eye Diagram Testing
When performing USB 2.0 compliance eye-diagram testing with a host or the downstream port of a HUB
with the TUSB213, a scenario can occur where the TUSB213 signal boosting is not enabled. This can
occur when the test packets are being transmitted before the USB test fixture is connected to the
TUSB213. This scenario does not occur during device compliance eye-diagram testing as the USB test
fixture must always be connected while testing a device. This scenario only occurs during the compliance
testing with the USB test fixtures and does not affect normal operation with a host, HUB, or device.
Closely following the test procedures provided by the scope equipment vendor and USB-IF (links provided
in
) will avoid this scenario. Specifically, the USB HS test fixture should be connected prior to
executing the
TEST PACKETS
using the HSETT test tool. Alternatively, if the test fixture is hot-plugged to
the host or downstream HUB port after the command to send test packets has already been entered using
the HSETT tool, it is necessary to select
TEST PACKETS
and click “Execute” again after the test fixture is
connected to ensure the TUSB213 detects a compliance test set-up.
The following generic procedure can be used to take the USB 2.0 compliance eye-diagrams
(refer
to
for details):
1. Connect the USB test fixture to the host, downstream HUB (+ TUSB213) port or device under test.
2. Configure the host, or HUB, or device using xHSETT or HSETT to send test packets using the
procedure detailed in the HSETT documentation.
3. Start sending test packets
4. Capture test packet on scope to display eye (running compliance software on the scope)
USB 2.0 compliance eye-diagrams can be taken on host, device, and HUB platform ports configured with
the TUSB213 using the
