The CMU0 PLL generates the high-speed clock from the input reference clock. The PFD
tracks the VCO output with the input reference clock.
For more information about transceiver input reference clocks, refer to the
Clocking in Stratix IV Devices
The VCO in the CMU0 PLL is half rate and runs at half the serial data rate. To generate
the high-speed clock required to support a native data rate range of 600 Mbps to
8.5 Gbps, the CMU0 PLL uses two multiplier blocks (/M and /L) in the feedback path
(shown in
The ALTGX MegaWizard Plug-In Manager provides the list of input reference clock
frequencies based on the data rate you select. The Quartus II software automatically
selects the /M and /L settings based on the input reference clock frequency and serial
data rate.
The CMU0 and CMU1 PLLs have a dedicated pll_locked signal that is asserted to
indicate that the CMU PLL is locked to the input reference clock. You can use the
pll_locked signal in your transceiver reset sequence, as described in the
