The 89HP0504UB Repeater USB3 Evaluation Board is designed to enable quick in-system testing of IDT’s 4-channel, 5Gbps USB3 Repeater IC product.
This board provides a 2-lane connection from USB3 host through the Repeater to an HDD, memory stick or other USB3 device.  One of the lanes includes an 18-inch trace segment to emulate PCB connectivity.  This Evaluation Board is powered from the USB host connector.  It is connected using two USB3 cables to a host controller and storage device.
The 89HP0504UB Repeater uses pin-strap configuration, and this Evaluation Board implements a three-position DIP switch for simple setting of receiver equalization and transmitter swing and emphasis.  Each of the 4-channels is independently configured via the switches.
