Abstract:
A receiver for a serial link port that is enhanced by a clock-data-recovery loop connected to the forwarded clock signal lane. The receiver includes a phase interpolation means controlled by a phase position logic which gets its update signal from local phase update signals of the clock-data-recovery loop via a digital low pass filter. The receiver also provides a global phase update source selection logic to control which clock-data-recovery loop is distributing phase update information, and which clock-data-recovery loop is receiving phase update information based on the clock analysis block.
