Notes to
(1) High-speed clock.
(2) Low-speed clock.
(3) Bonded common low-speed clock path.
(4) These PLLs have restricted clock driving capability and may not reach all connected channels. For details, refer to

bonded configurations. In these configurations, each bonded channel selects the
high-speed clock from one the supported PLLs. The high-speed clock in each bonded
channel feeds the respective serializer for parallel to serial operation. The common
bonded low-speed clock feeds to each bonded channel that is used for the following
blocks in each transmitter PCS channel:
