Receive Muting - Hardware mode
Connecting this pin ‘High’ will mute (force to ground) the outputs RPOS_n/
RNEG_n when a LOS condition occurs, to prevent data chattering. This pin
is internally pulled "low" consequently muting is normally disabled.
NOTES:
1.
Internally pulled "Low" with 50k
resistor.
2.
In Hardware mode, all receive channels share the same RXMUTE
control function.

Receive External Resistor Control Pins - Hardware mode
Receive External Resistor Control Pin 0
Receive External Resistor Control Pin 1
These pins are used to determine the value of the external Receive fixed
resistor according to the following table:
NOTE: These pins are internally pulled “Low” with 50k
resistor.

Receive Clock Edge - Hardware Mode
Set this pin "High" to sample RPOS_N/RNEG_n on the falling edge of
RCLK_n. With this pin tied "Low", output data are updated on the rising edge
of RCLK_n.
Microprocessor Type Select Input pin 1 - Host mode
This pin along with PTS2 (pin 107) is used to select the microprocessor
NOTE: This pin is internally pulled "Low" with a 50k
resistor.
