SDO
RxMON
I/O
Serial Data Output:
This pin serially outputs the contents of the specified Command Register during
Read Operations. The data is updated on the falling edge of the SClk and this
pin is tri-stated upon completion of data transfer.
NOTE: If configured in Hardware Mode, this pin functions as RxMON.
97
RESET
I
Register Reset:
Setting this input pin "Low" causes to reset the contents of the Command Reg-
isters to their default settings and default operating configuration
NOTE: This pin is internally pulled up.
28
INT
LOSMUT
I/O
INTERRUPT Output:
A transition to “Low” indicates that an interrupt has been generated. The inter-
rupt function can be disabled by setting the interrupt enable bit to “0” in the
Channel Control Register.
NOTES:
1.
In Hardware mode, this pin functions as LOSMUT.
2.
This pin will remain asserted “Low” until the interrupt is serviced.

JATx/Rx
I
Jitter Attenuator Path Select
In Hardware Mode, tie this pin “High” to select the Jitter Attenuator in the Trans-
mit Path . Connect this pin “Low” to select the Jitter Attenuator in the Receive
Path. This applies to all channels.
NOTE: This pin is internally pulled down.
