Chapter 3: Configuring Multiple Protocols and Data Rates in Stratix IV Devices
Combination Requirements When You Enable Channel Reconfiguration
February 2011 Altera Corporation
Example 12 shows the requirements.
Example 12
Consider that you intend to run four channels within the transceiver block to switch
between GIGE and SONET OC48 data rates. Assume that by default two channels run
at GIGE data rates and the other two channels run at SONET OC48 data rates.
Assume that Instance1 with two channels running at GIGE data rate is created with
the configuration, as listed in
Table 3–16. Combining Requirements with the Use Alternate CMU PLL Option Enabled—
Instance 1 for Example 12
Create Instance 2 with the following parameters to enable the Quartus II software to
share CMU PLLs between the two instances.
