OIF CEI-56G LR PAM4 Calibrations

This test depends on the values configured for the following settings:
• All LR calibrations performed previously:

•

Amplitude Calibration

•

SJ Calibration

•

UUGJ Calibration

Parameters

Refer to “

Calibration Parameters in Debug Mode

” on page 122.

Procedure

This test uses the QPRBS31-CEI pattern.

Results

This calibration contains the results for all Transmitter Electrical Output

and Jitter Output parameters for the selected Test Channel Configuration,

in tabular format.

Transmitter Electrical Output Specification
• Transition Time
• Level Separation Mismatch Ratio
• Signal-to-Noise-and-Distortion-Ratio

Transmitter Output Jitter Specification
• Uncorrelated Jitter (J4u) (time interval from 0.005% to 99.995% of the

probability distribution)

• Uncorrelated jitter RMS (Jrms) (standard deviation of the probability

distribution)
