The CRU has a built-in switchover circuit to select whether the PLL VCO
is aligned by the reference clock or the data. The optional port
rx_freqlocked monitors when the CRU is in locked-to-data mode.
In the automatic mode, the CRU PLL must be within the prescribed PPM
frequency threshold setting of the CRU reference clock for the CRU to
switch from locked-to-reference to locked-to-data mode.
The automatic switchover circuit can be overridden by using the optional
ports rx_locktorefclk and rx_locktodata.
possible combinations of these two signals.
If the rx_locktorefclk and rx_locktodata ports are not used, the
default is auto mode.
Deserializer (Serial-to-Parallel Converter)
The deserializer converts a serial bitstream into 8, 10, 16, or 20 bits of
parallel data. The deserializer receives the LSB first.
