17.30. Merging TX PLLs In Multiple Transceiver PHY Instances

This section describes merging instances of the transceiver PHY.

The Intel® Quartus® Prime Fitter can merge the TX PLLs for multiple transceiver PHY IP cores under the following conditions:

  • The PLLs connect to the same reset pin.
  • The PLLs connect to the same reference clock.
  • The PLLs connect to the same Transceiver Reconfiguration Controller.

The following figure illustrates a design where the CMU PLL in channel 1 provides the clock to three Custom PHY channels and two 10GBASE-R PHY channels.
