KC705 Evaluation Board
UG810 (v1.3) May 10, 2013
Chapter 1:
KC705 Evaluation Board Features
lists the SFP+ module control and status connections to the FPGA.
10/100/1000 Tri-Speed Ethernet PHY
[
, callout
The KC705 board utilizes the Marvell Alaska PHY device (88E1111) U37 for Ethernet
communications at 10, 100, or 1000 Mb/s. The board supports MII, GMII, RGMII, and
SGMII interfaces from the FPGA to the PHY (
). The PHY connection to a
user-provided Ethernet cable is through a Halo HFJ11-1G01E RJ-45 connector (P3) with
built-in magnetics.

Notes:
1. On KC705 boards prior to Rev 1.1, SFP+ connector P5 pin 18 TD_P is connected to net
SFP_TX_N, and pin 19 TD_N is connected to net SFP_TX_P.
