Figure 2-38: Receiver Termination Configuration

For selected Altera devices, use the RX Impedance pull-down menu to select a termination configura‐

tion. You can also customize the termination configuration by selecting the Custom option. When the

Custom RX Impedance method is chosen, the termination can be configured as follows:

• Ideal TX termination—The transmitter is ideal with a 50 ohms (single-ended) termination.

• Non-ideal TX termination—Select one of the following options:

• R—Transmitter impedance is modeled as a resistance R ohms (single-ended).

• R//C1—Transmitter impedance is modeled as an RC network with a parallel resistor (in ohms)

and a capacitance (in pF).

• File Input (Frequency Real Imaginary)—Transmitter impedance is modeled by a frequency-

dependent complex impedance table described in the input file.

For an Altera transmitter, the default termination configurations are automatically selected and

specified.
