External Reset.
Active low input that performs external hardware reset of
device. Resets all internal logic to a known state. Clock out-
puts are tristated during reset. After rising edge of RST sig-
nal, the Si5322 will perform an internal self-calibration.
This pin has a weak pull-up.
Frequency Table Select.
Selects SONET/SDH, datacom, or SONET/SDH to datacom
frequency table.
L = SONET/SDH.
M = Datacom.
H = SONET/SDH to Datacom.
The pin has a weak pull-up and weak pull-down and
defaults to M.
Some designs may require an external resistor voltage
divider when driven by an active device that will tri-state.
CKIN1 Loss of Signal.
Active high loss-of-signal indicator for CKIN1. Once trig-
gered, the alarm will remain active until CKIN1 is validated.
0 = CKIN1 present.
1 = LOS on CKIN1.
