Figure 1–8. CMU0 Clock Divider Block
Notes to
(1) The Quartus II software automatically selects all the divider settings based on the input clock frequency, data rate, deserialization width, and
(2) The high-speed serial clock is available to all the transmitter channels in the transceiver block. In a ×8 configuration, only the CMU0 clock divider
(3) If the byte serializer block is enabled in bonded channel modes, the coreclkout clock output is half the frequency of the low-speed parallel clock.

of the master transceiver block provides the high-speed serial clock to all eight channels.
Otherwise, the coreclkout clock output is the same frequency as the low-speed parallel clock.

The clock divider is only available only in the CMU0 block and is used in bonded
functional modes.
Figure 1–8
Each transmitter channel contains a local clock divider block used automatically by
the Quartus II software for non-bonded functional modes (for example, ×1 PCIe,
GIGE, SONET/SDH, and SDI mode). This block allows each transmitter channel to
run at /1, /2, or /4 of the CMU PLL output data rate.
