KC724 - Differential pairs in Master UCF on Early Access site have LVCMOS IOSTANDARD settings

描述

The KC724 Master UCF file on the Early Access site (http://www.xilinx.com/member/7_ea_kc724/index.htm) lists the IOSTANDARD for differential pairs AJ3, AK3, B25 and C25 as LVCMOS18. Is this correct?

解决方案

AJ3 and AK3 are CM_LVDS3_N / P pins, while B25 and C25 are LVDS_OSC_N / _P pins.

Differential pairAJ3 AK3 should havethe IOSTANDARD LVDS associated with them.
Differential pair B25 C25 should have the IOSTANDARD LVDS_25 associated with them.

This has been corrected in v1.0 of the Master UCF, available on the public KC724 Board Files page: http://www.xilinx.com/support/documentation/kc724_14-3_bf.htm
