Chapter 3: Configuring Multiple Protocols and Data Rates in Stratix IV Devices
Sharing CMU PLLs

Table 3–3. ALTGX MegaWizard Plug-In Manager Settings for Example 1
You can force the placement of the transceiver channels to a specific transceiver block
by assigning pins to tx_dataout and rx_datain. Otherwise, the Quartus II software
selects a transceiver bank.
Figure 3–1
combines the transceiver channel instances. Because the RX CDR is not shared
between channels, only the CMU PLL is shown.
Note to
(1) The Specify base data rate option is 4.25 Gbps for all four instances. Given that the CMU PLL bandwidth setting
and input reference clock are the same and that the pll_powerdown ports are driven from the same logic or pin,
the Quartus II software shares a single CMU PLL that runs at 4.25 Gbps.
