USB 3.2 ENGINEERING CHANGE NOTICE Bit-level re-timers which use the recovered clock from the input data stream as the input clock for the transmitter can pass on low frequency jitter, which can in turn result in accumulation of excessive low frequency jitter in systems with cascaded bit -level Retimers. Current JTF Jitter Gain limit was chosen analytically, empirical results of early Retimers implementations show a higher realistic jitter gain below 500kHz with no impact on Jitter tolerance requirements contained in Section 6.8.5. This ECN changes the Max. Limit of JTF Jitter Gain parameter.
