I want to receive a clock over LVDS from a dedicated clock input pin on my Cyclone V device.Is there a 100 Ω differential termination resistor on the dedicated clock input pin built into the FPGA?

Tools: Quartus® II
Device: Cyclone® V
Category: Device


In Cyclone V devices, the dedicated clock input pins as well as the I/O pins have 100 Ω On-Chip Termination inside the FPGA and support True LVDS with On-Chip Termination (Rd). increase.

At that time, in the Assignment Editor,

To : <input pin>
Assignment Name : Input Termination
Value: Differential

Please compile with the following restrictions.
After compiling, check that Termination is set to Differential in Fitter ⇒ Resource Section ⇒ Input Pins in the compilation report.

For more information, please refer to the device handbook below.
