NC
No Connect.
These pins must be left unconnected for normal operation.
3RST
ILVCMOS
External Reset.
Active low input that performs external hardware reset of
device. Resets all internal logic to a known state and forces the
device registers to their default value. Clock outputs are dis-
abled during reset. After rising edge of RST signal, the device
will perform an internal self-calibration when a valid input signal
is present.
This pin has a weak pull-up.

3-Level
Frequency Table Select.
This pin selects SONET/SDH, datacom, or SONET/SDH to
datacom frequency translation table.
L = SONET/SDH.
M=Datacom.
H = SONET/SDH to Datacom.
This pin has both weak pull-ups and weak pull-downs and
defaults to M. Some designs may require an external resistor
voltage divider when driven by an active device that will tri-
state.

Supply
Ground.
This pin must be connected to system ground. Minimize the
ground path impedance for optimal performance.

LVCMOS
CKIN1 Invalid Indicator.
This pin is an active high alarm output associated with CKIN1.
Once triggered, the alarm will remain high until CKIN1 is vali-
dated.
0 = No alarm on CKIN1.
1 = Alarm on CKIN1.
