UltraScale GTH and GTY transceivers reference clock AC coupling capacitor value
描述
The Kintex UltraScale GTH User Guide (UG576 v1.0) shows the AC coupling capacitor value for the reference clock as 0.1uF and the Virtex UltraScale GTY User Guide (UG578) shows the value as 0.01uF.
Which value should be used?
解决方案
Though both will work for most applications, the recommendation is to use 0.01 uF.
The Kintex UltraScale GTH user guide will be updated to reflect this.
