REFCLK_8
All 24 channels have access to all nine reference clock options. This provides:
• Full flexibility on selecting reference clocks on a per-channel basis
•
Channel bonding enabled using refclk[0]
In full duplex mode, each channel can dynamically select any of the nine reference
clocks. If RX and TX channels require different clock frequencies, refclk[1] must be
used as one of the two clocks.
