3.3.1. x1 Clock Lines

The x1 clock lines route the high speed serial clock output of a PLL to any channel within a transceiver bank. The low speed parallel clock is then generated by that particular channel's local clock generation block (CGB). Non-bonded channel configurations use the x1 clock network.

The x1 clock lines can be driven by the ATX PLL, fPLL, or by either one of the two channel PLLs (channel 1 and 4 when used as a CMU PLL) within a transceiver bank.
