KC705 User Guide UG810 (v1.6.1) - Table 1-9 - SYSCLK_N / _P I/O Standard

描述

(UG810) KC705 Evaluation Board User Guide (v1.6.1) lists the Clock Source to FPGA U1 Connections in Table 1-9.

What is the correct I/O Standard for SYSCLK_N and SYSCLK_P?

解决方案

SYSCLK_N and SYSCLK_P connect to U1 FPGA Pins AD11 and AD12 respectively.

AD11 and AD12 are in Bank 33 of the XC7K325T device.

Bank 33 is a HP I/O Bank.

The LVDS I/O standard is only available in the HP I/O banks and requires a VCCO of 1.8V.

The I/O Standard in Table 1-9 for SYSCLK_N and SYSCLK_P should be LVDS, not LVDS_25.

Table 1-9 is updated in UG810 v1.6.2:
