5.4.2.1 Muting the Recovered Data with LOS condition:
When the LOS condition is declared, the clock recovery circuit locks into the reference clock applied to the
ExClk pin and output this clock on the RxClk output. The data on the RPOS and RNEG pins can be forced to
zero by pulling the LOSMUT pin “High” (in Hardware Mode) or by setting the LOSMUT bits in the individual
channel control register to “1” (in Host Mode).
NOTE: When the LOS condition is cleared, the recovered data is output on RPOS and RNEG pins.
