644.53125
MHz
Specifies the transceiver reference clock frequency.
The default value for the Input clock frequency is
lane rate/16. Sample values of N include 80, 64, 50,
40, 32, 25, 20, 16, 12.5, 10, and 8.
Altera recommends that you select the highest
frequency among the available options in the
drop-down list.
For Arria 10 source designs, set this parameter to
none.

The effective data rate at the output of the
transceivers, incorporating transmission and other
overheads.
The parameter editor automatically calculates this
value by adding the input data rate with transmis‐
sion overheads to provide you with a selection of
user clock frequency.

Transceiver Reconfiguration Controller for Stratix V and Arria V GZ
Designs
If your design targets Stratix V or Arria V GZ devices, the transceiver reconfiguration controller is not
included in the generated IP core. To create a complete system, refer to the design example block diagram
on how to connect the transceiver reconfiguration controller.
(2)
The clock frequency value is useful if you want to simulate designs at different data rates. You should
apply the displayed value in your testbench parameters.
