Overview
Description
The 89KTT0832P retimer evaluation board is designed to enable quick in-system testing of Renesas’s 16-lane, 8Gbps, PCIe 3.0 Retimer IC product.
This board features a 16-lane PCIe connection from host through the Retimer to an end-point device installed in the 16-lane PCIe slot. The eval board is used by inserting it into a desktop PC or server, and then plugging an end point adapter card (SAS, Ethernet, graphics, etc.) into the 16-lane slot on top. Passive trace cards can be used to extend the data signal to emulate a planned system design. Note that the resulting card stack will require an open chassis test environment.
The board provides a USB-to-I2C bridge circuit which allows convenient connection to a PC for accessing the retimers control and status registers via Renesas’s Configuration Utility GUI for Windows. Software tools for signal eye capture are available. Direct I2C and JTAG interfaces are also provided to access all receiver, transmitter, and other device registers
Features
- Uses one 89HT0832P PCIe3 retimer
- 16-lane PCIe adapter card with full PCIe protocol support, including all equalization procedure phases 0 - 3
- Configurable via USB, I2C or JTAG interfaces using Renesas Windows GUI
- EEPROM supports automatic download of configuration data to the sp89HT0832P retimer
- Allows individual channel configuration
- Switches define power-on initial state
- Multiple power and clock connection options
- Card format: 8.5” x 4.75”. Note non-standard form factor requires an open chassis for use
- Works with passive trace cards to extend FR4 traces
