Notes:
① The measured value is the net output value of the transmitter, the default pre-emphasis/de-emphasis parameters;
② 30cm RF test cable, output measured value in “high power output” mode;
③ Measured with 26.5625 Gb/s NRZ signal;
④ Measure random jitter after jitter separation;
⑤ The measured value is the net input value at the receiver;
⑥When the input amplitude is less than 100 mVpp, the corresponding bit error rate may reach e-3 or even LOS;
