Each transceiver block contains two CMU blocks, which contain a CMU phase-locked
loop (PLL) that provides clocks to all the transmitter channels in the same transceiver
block. These two CMU blocks can provide two independent high-speed clocks per
transceiver block.
The CMU PLL is also known as the TX PLL.
The CMU PLLs in CMU0 and CMU1 are identical and each transmitter channel in the
transceiver block can receive a high-speed clock from either of the two CMU PLLs.
However, the CMU0 block has an additional clock divider after the CMU0 PLL to support
bonded functional modes where multiple channels share a common clock to reduce
skew between the channels. With the ALTGX MegaWizard Plug-In Manager, you can
select the bonded functional modes used in ×4 Basic, PCIe, and XAUI.
