Description
Data Sheet
Lock Indicator (Output).
This output goes to a logic high when the PLL is frequency
locked to the selected input reference.
Reference Failure Indicator (Output).
A logic high at this pin indicates that the REF
reference frequency is exhibiting abrupt phase or frequency changes.

Reset (Input).
A logic low at this input resets the device. On power up, the RST pin
must be held low for a minimum of 300 ns after the power supply pins have reached
the minimum supply voltage. When the RST pin goes high, the device will transition
into a Reset state for 3 ms. In the Reset state all clock and frame pulse outputs will be
forced into high impedance.
Oscillator Master Clock (Output).
For crystal operation, a 20 MHz crystal is connected
from this pin to OSCi. This output is not suitable for driving other devices. For clock
oscillator operation, this pin must be left unconnected.
Oscillator Master Clock (Input).
For crystal operation, a 20 MHz crystal is connected
from this pin to OSCo. For clock oscillator operation, this pin must be connected to a
clock source.
