2.2.3.1.1. Non-Bonded Channel Configurations

In non-bonded configurations, the receiver standard PCS requires both the parallel clock (recovered) and parallel clock from the clock divider.

Depending on the configuration, the receiver PCS may require the parallel clock from the clock divider that is used for the transmitter PCS.

Note: In non-bonded configurations, the receiver 10G PCS uses only the parallel clock (recovered) for all its blocks.

Figure 66. Three Channels Configured in Non-Bonded ConfigurationThe figure shows three channels configured in non-bonded configuration. They use the receiver standard PCS that does not use a rate match FIFO. The CDR of each channel recovers the serial clock (recovered) from the incoming data and generates the parallel clock (recovered) by dividing the serial clock (recovered). Depending on the configuration, the receiver PCS may also use the parallel clock from the clock divider that is generated by the local clock divider for the transmitter.


Note: For more information about the clocking scheme used in different configurations, refer to the Transceiver Configurations in Stratix V Devices chapter.
