The CRU has a built-in switchover circuit to select whether the
voltage-controlled oscillator of the PLL is trained 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 following conditions must be met 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_lockedtorefclk and rx_locktodata.
possible combinations of these two signals.
If the rx_lockedtorefclk and rx_locktodata ports are not used,
the default is auto mode.

The CRU PLL is within the prescribed PPM frequency threshold
setting (125 PPM, 250 PPM, 500 PPM, 1,000 PPM) of the CRU
reference clock.
The reference clock and CRU PLL output are phase matched (phases
are within .08 UI).
Multiplication factors 2, 4, and 5 can only be achieved with the use of the pre-
divider on the
