What is the value of the transceiver differential Rx On-Chip Termination (OCT) on Arria II GX devices?

Environment

  • Arria® II GX FPGA
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The value of the transceiver differential Rx On-Chip Termination (OCT) on Arria® II GX devices is the combination of the two single ended OCT resistors to the Vcm generator.

Figure 1-24 of the Arria II GX transceiver handbook shows the combined value of two individual single ended resistors

For example, each resistor is 50 Ohms making a combined value of 100 Ohms.
