I Receive Data Muting

When a LOS condition occurs, the outputs RPOS_n/RNEG_n will be muted,

(forced to ground) to prevent data chattering.

Tie this pin “Low” to disable the muting function.

NOTES:

1. This pin is internally pulled “High” with a 50kΩ resistor.

2. In Hardware mode, all receive channels share the same RXMUTE

control function.
