Virtex-6 System Monitor - Maximum DCLK frequency revised down to 80 MHz

描述

The initial specification for the DCLK was 250 MHz. This has been revised down to 80 MHz.

解决方案

The maximum conversion rate of the System Monitor is still 200 ksPs because the ADCCLK is still 5.2 MHz.

The ADCCLK = DCLK / DCLK Divisior (the DCLK divisor is set in the Config Reg #2).

The effect of violating the maximum DCLK of 80 MHz is that it can result in a race condition in the System Monitor logic which results in incorrect readings. The problem occurs at temperatures between 55 C and 80 C only.
