interface implemented in Stratix and Stratix GX devices.
RXDATA[15..0] is received from the OC-192 SERDES on the differential
I/O pins of the Stratix or Stratix GX device. The receiver SERDES
converts the high-speed serial data to parallel. You can generate the
clocks required in the SERDES for parallel and serial data conversion
from the received RXCLK. RXCLK is inverted (phase-shifted by 180 ) to
capture received data. While normal I/O operation guarantees that data
is captured, it does not guarantee the parallelization boundary, which is
randomly determined based on the power up of both communicating
devices. The SERDES has embedded data realignment capability, which
can be used to save logic elements (LEs).
