Figure 1–32. Clock Distribution in Non-Bonded Channel Configuration for Transceivers in F484 and
Larger Packages
Notes to
(1) High-speed clock.
(2) Low-speed clock.
(3) These PLLs have restricted clock driving capability and may not reach all connected channels. For details, refer to
The transceiver datapath clocking varies in non-bonded channel configuration
depending on the PCS configuration.
Figure 1–33
each channel selects the high- and low-speed clock from one of the supported PLLs.
The high-speed clock feeds to the serializer for parallel to serial operation. The
low-speed clock feeds to the following blocks in the transmitter PCS:
■
■
■
When the byte serializer is enabled, the low-speed clock frequency is halved before
feeding into the read clock of TX phase compensation FIFO. The low-speed clock is
available in the FPGA fabric as tx_clkout port, which can be used in the FPGA
fabric to send transmitter data and control signals.
