Description The typical rules for sharing a Tx PLL between multiple transceiver instances on Stratix® V, Arria® V, and Cyclone® V transceiver devices are as follows. All transceiver instances intended to share a Tx PLL must have a common refclk input. All transceiver instances intended to share a Tx PLL must have a common Tx PLL VCO (base data rate) frequency. All transceiver instances intended to share a Tx PLL must have common Tx PLL reset or power down inputs. All transceiver instances intended to share a Tx PLL must have common reconfiguration controller. Sharing Tx PLLs for designs that also implement dynamic reconfiguration require a Quartus® II XCVR_TX_PLL_RECONFIG_GROUP QSF assignment for each transceiver sharing the Tx PLL. Failure to adhere to the above requirements may result in a Quartus® II No Fit error. You can refer to the device specific handbook or PHY IP Userguide for further information.
