Twisted Pair Cable Wire Gauge Select - Hardware Mode
Connect this pin “High” to select 26 Gauge wire. Connect this pin “Low” to select 22
and 24 gauge wire for all channels.
NOTE: Internally pulled “Low” with a 50k
Ω resistor.

Driver Failure Monitor Channel _0:
This pin transitions “High” if a short circuit condition is detected in the transmit driver of
Channel _0, or no transmit output pulse is detected for more than 128 TCLK_0 cycles.

I
Automatic Transmit “All Ones” Pattern - Hardware Mode
A "High" level on this pin enables the automatic transmission of an "All Ones" AMI pat-
tern from the transmitter of any channel that the receiver of that channel has detected
an LOS condition. A "Low" level on this pin disables this function.
Note: All channels share the same ATAOS control function.
Microprocessor Clock Input - Host mode
NOTE: This pin is internally pulled “Low” for asynchronous microprocessor interface
when no clock is present.

I
O
Transmitter Transformer Ratio Select - Hardware mode
In external termination mode (TXTSEL = 0), setting this pin “High” selects a trans-
former ratio of 1:2 for the transmitter. A “Low” on this pin sets the transmitter trans-
former ratio to 1:2.45. In the internal termination mode the transmitter transformer
ratio is permanently set to 1:2 and the state of this pin is ignored.
Interrupt Output - Host mode
This pin is asserted “Low” to indicate an alarm condition.
NOTE: This pin is an open drain output and requires an external 10k
Ω pull-up resistor.
RESET
T8
I
Hardware Reset (Active “Low”):
When this pin is tied “Low” for more than 10s, the device is put in the reset state.
Exar recommends initiating a Hardware reset upon power up.
NOTE: This pin is internally pulled “High” with a 50k
Ω resistor.
SR/DR
K4
I
Single-Rail/Dual-Rail Data Format:
Connect this pin “Low” to select transmit and receive data format in Dual-Rail mode. In
this mode, HDB3 or B8ZS encoder and decoder are not available.
Connect this pin “High” to select single-rail data format.
NOTE: Internally pulled “Low” with a 50k
Ω resistor.
