CMU1 Channel
The CMU1 channel, shown in
high-speed clock to the transmitter channels within the transceiver block. The
CMU1 PLL is similar to the CMU0 PLL (refer to
The CMU1 PLL generates the high-speed clock that is only used in non-bonded
functional modes. The transmitter channels within the transceiver block can receive a
high-speed clock from either of the two CMU PLLs and uses local dividers to provide
clocks to its PCS and PMA blocks.
For more information about using two CMU PLLs to configure transmitter channels,
refer to the
Power Down CMU1 PLL
You can power down the CMU1 PLL by asserting the pll_powerdown signal.
For more information, refer to the
chapter.
Configuring CMU Channels as Transceiver Channels
You can configure the two CMU channels in the transceiver block of Stratix IV GX
and GT devices as full-duplex PMA-only channels to run between 600 Mbps and
6.5 Gbps.
