Description
3.3 V Power Pins.
Reference Monitor (Output). This pin has multiple selectable outputs.
Lock Detect (Output). This pin has multiple selectable outputs.
Power Supply for Charge Pump (CP); VS ≤ VCP ≤ 5.25 V. VCP must still be connected
to 3.3 V if the PLL is not used.
Charge Pump (Output). This pin connects to an external loop filter. This pin can
be left unconnected if the PLL is not used.
Programmable Status Output.
Reference Select. It selects REF1 (low) or REF2 (high). This pin has an internal
30 kΩ pull-down resistor.
Manual Synchronizations and Manual Holdover. This pin initiates a manual
synchronization and is used for manual holdover. Active low. This pin has an
internal 30 kΩ pull-up resistor.
No Connect. These pins can be left floating.
Along with CLK, this pin is the differential input for the clock distribution section.
Along with CLK, this pin is the differential input for the clock distribution section. If a
single-ended input is connected to the CLK pin, connect a 0.1 μF bypass capacitor
from this pin to ground.
