DESCRIPTION

Receive Muting upon LOS Command Input/READY or DTACK Output:

The exact function of this Input/Output pin depends upon whether the

XRT83L34 device has been configured to operate in the HOST or Hardware

Mode, as described below.

Hardware Mode Operation - Receive Muting upon LOS Command Input

pin:

This input pin permits the user to enable or disable the "Muting upon LOS"

feature within the XRT83L34 device. If the user enables the "Muting upon

LOS" feature, then the Receive Section of each channel (within the

XRT83L34 device) will automatically MUTE their own RPOS_n/RNEG_n out-

put pins (e.g., force to ground) for the duration that they are declaring the

LOS defect condition, as described below.

RDY_DTACK

73

LOW - Disables the "Muting upon LOS" feature for all four (4)

HIGH - Enables the "Muting upon LOS" feature.

NOTES:

1. Internally pulled "Low" with 50kΩ resistor.

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

control function.
