Arria II Device Handbook Volume 2: Transceivers
Multiple Channels Sharing Two CMU PLLs
1
In some cases, a single CMU PLL is not sufficient to run the transmitter channels
within a transceiver block at the desired data rates.
Use a second CMU PLL if you want to combine channels that require different
configurations, such as:
■
■
■
Example 2
Consider a design that requires four channels set up in a Receiver and Transmitter
configuration in the same transceiver block at the serial data rates shown in
Table 3–2. Configuration for Example 2 for Arria II Devices
Assume that instance 0, 1, and 2 are driven from the same clock source and have the
same CMU PLL bandwidth settings. In this case, you can use one CMU PLL for
instance 0, 1, and 2. For the ALTGX MegaWizard Plug-In Manager settings that enable
the Quartus II software to share the same CMU PLL, refer to
page
You can force the placement of transceiver channels to a specific transceiver block by
assigning pins to the tx_dataout and rx_datain pins of the four ALTGX instances.
Otherwise, the Quartus II software selects a transceiver block.
Figure 3–2
software combines the transceiver channels within the same transceiver block.
Because the RX CDR is not shared between channels, only the CMU PLLs are shown.
You must connect the pll_powerdown port of instance 0, 1, and 2 to the same logic
output to share the same CMU PLL for these instances.
