DESCRIPTION
RxON

I
Receive On/Off Input
Upon power up, the receivers are powered off. Turning the receivers On or Off
can be selected through the microprocessor interface by programming the
appropriate channel register if the hardware pin is pulled "High". If the hard-
ware pin is pulled "Low", all channels are automatically turned off.
NOTE: Internally pulled "Low" with a 50K
resistor.
RxTSEL

I
Receive Termination Control
Upon power up, the receivers are in "High" impedance. Switching to internal
termination can be selected through the microprocessor interface by program-
ming the appropriate channel register. However, to switch control to the hard-
ware pin, RxTCNTL must be programmed to "1" in the appropriate global
register. Once control has been granted to the hardware pin, it must be pulled
"High" to switch to internal termination.
NOTE: Internally pulled "Low" with a 50k
resistor.
RLOS

O
Receive Loss of Signal (Global Pin for All 14-Channels)
When a receive loss of signal occurs for any one of the 14-channels according
to ITU-T G.775, the RLOS pin will go "High" for a minimum of one RCLK cycle.
RLOS will remain "High" until the loss of signal condition clears.
See the
Receive Loss of Signal section of this datasheet for more details.
NOTE: This pin is for redundancy applications to initiate an automatic switch to
the backup card. For individual channel RLOS, see the register map.

Receive Clock Output
RCLK is the recovered clock from the incoming data stream. If the incoming
signal is absent or RxON is pulled "Low", RCLK maintains its timing by using
an internal master clock as its reference. Software control (RCLKE) allows
RPOS/RNEG data to be updated on either edge of RCLK.
NOTE: RCLKE is a global setting that applies to all 14 channels.
