RPOS/RNEG/RCLK
The digital output data can be programmed to either single rail or dual rail formats. Figure 12 is a timing
diagram of a repeating "0011" pattern in single-rail mode. Figure 13 is a timing diagram of the same fixed
pattern in dual rail mode.

RxMUTE (Receiver LOS with Data Muting)
The receive muting function can be selected by setting RxMUTE to "1" in the appropriate global register. If
selected, any channel that experiences an RLOS condition will automatically pull RPOS and RNEG "Low" to
prevent data chattering. If RLOS does not occur, the RxMUTE will remain inactive until an RLOS on a given
channel occurs. The default setting for RxMUTE is "0" which is disabled. A simplified block diagram of the
RxMUTE function is shown in Figure 14.
