5.4.3 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_n pin and output this clock on the RxClk_n output.In Single Frequency Mode (SFM), the clock recovery
locks into the rate clock generated and output this clock on the RxClk_n pins. The data on the RPOS_n and
RNEG_n pins can be forced to zero by pulling the LOSMUT pin “High” (in Hardware Mode) or by setting the
LOSMUT_n 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_n and RNEG_n pins.
