(4) Tx Common Mode AC noise decreases at lower levels of EQ gain.
(5) Tested with a valid idle signal on the input with peak differential voltage of 6 mV.
(6) Additive random jitter is given in RMS value by the following equation: RJ_ADD = √[(Output Jitter)² - (Input Jitter)²]. Typical input jitter for
these measurements is 150 fs rms.
