1.2.3.3. Channel PLL (CMU/CDR PLL)

A channel PLL resides locally within each transceiver channel. Its primary function is clock and data recovery in the transceiver channel when the PLL is used in clock data recovery (CDR) mode. The channel PLLs of channel 1 and 4 can be used as transmit PLLs when configured in clock multiplier unit (CMU) mode. The channel PLLs of channel 0, 2, 3, and 5 cannot be configured in CMU mode and therefore cannot be used as transmit PLLs.
