Document Table of Contents Rate Match FIFO

The Rate Match FIFO (or clock compensation FIFO) compensates for minute frequency differences between the local clock (sometimes referred to as PLD soft IP clock, or PLD system clock) and the recovered clock. This is achieved by inserting and deleting SKP characters in the data stream to keep the FIFO from going empty or full respectively.
