The 89HP0504U Repeater Evaluation Board is designed to enable quick in-system testing of Renesas’s 4-channel, 5Gbps USB3 Repeater IC product.

This board provides a 2-lane connection from a 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 via two USB3 cables to a host controller and storage device or other peripheral.

The 89HP0504U Repeater is I2C configured, and this Evaluation Board provides a USB-to-I2C bridge circuit which allows simple connection to a PC for accessing the Repeaters control and status registers via Renesas’s Repeater Configuration Utility (GUI).  The Repeaters receiver, transmitter, and other device configuration parameters can be easily adjusted using the GUI to provide optimum operation.  Device configuration can be stored in the on-board serial EEPROM, or saved as a data file, for later use.
