Figure 4-2: OIF VSR Channel Characteristics

The JNEye Channel Viewer shows that the channel has approximately 7.4 dB loss at 14 GHz. The four

crosstalk channels have an amplitude of about –45 dB at 14 GHz.

Use the ideal transmitter reference clock to simulate a more ideal case. The PLL in the Arria 10 GT

transmitter is enabled using ATX (LC) with low bandwidth configuration.

Use the JNEye’s link optimization algorithm to find optimal equalization settings for both the transmitter

and receiver. This demonstration uses the FIR => CTLE => DFE link optimization method.
