Clock Validation Time for LOS and FOS.
VALTIME sets the clock validation times for recovery
from an LOS or FOS alarm condition. When VAL-
TIME is high, the validation time is approximately
13 s. When VALTIME is low, the validation time is
approximately 100 ms .
Select 3.3 V V
This is an enable pin for the internal regulator. To
enable the regulator, connect this pin to the V
pins.
3.3 V Supply.
3.3 V power is applied to the V
supply bypassing/decoupling for this configuration is
indicated in the typical application diagram for 3.3 V
supply operation.
2.5 V Supply.
These pins provide a means of connecting the
compensation network for the on-chip regulator.
Ground.
Must be connected to system ground. Minimize the
ground path impedance for optimal performance of
the device.
External Biasing Resistor.
Establishes bias currents within the device. This pin
must be connected to GND through a 10 k Ω (1%)
resistor.
