implemented in Serial RapidIO functional mode.
Rate Match FIFO in Serial RapidIO Mode
In Serial RapidIO mode, the rate match FIFO is capable of compensating for up to
±100 PPM (200 PPM total) difference between the upstream transmitter and the local
receiver reference clock.
To enable the rate match FIFO in Serial RapidIO mode, the transceiver channel must
have both the transmitter and receiver channel instantiated. You must select the
Receiver and Transmitter option in the What is the operation mode? field in the
ALTGX MegaWizard Plug-In Manager. The 8B/10B encoder/decoder is always
enabled in Serial RapidIO mode.
Rate matcher is an optional block available for selection in SRIO functional mode.
However, this block is not fully compliant to the SRIO specification.
