RXMUTE

RDY_DTACK

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:

Internally pulled "Low" with 50k

Ω resistor.

In Hardware mode, all receive channels share the same RXMUTE

control function.

Ready Output (Data Transfer Acknowledge Output) - Host mode

See “Ready Output (Data Transfer Acknowledge Output) - Host Mode” on

page 8.

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

Ω 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 µPTS2 (pin 107) is used to select the microprocessor

type. See “Microprocessor Type Select Input Pins - Host Mode:” on page 9.

NOTE: This pin is internally pulled "Low" with a 50k

Ω resistor.
