Description
3.3 V Power Pins.
Reference Monitor (Output). This pin has multiple selectable outputs; see Table 54,
Register 0x01B.
Lock Detect (Output). This pin has multiple selectable outputs; see Table 54,
Register 0x1A.
Power Supply for Charge Pump (CP); V
Charge Pump (Output). Connects to external loop filter.
Status (Output). This pin has multiple selectable outputs; see Table 54, Register 0x017.
Reference Select. 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 also used for manual holdover. Active low. This pin has an
internal 30 kΩ pull-up resistor.
Loop Filter (Input). Connects to VCO control voltage node internally. This pin has
31 pF of internal capacitance to ground, which may influence the loop filter design
for large (>500 kHz) loop bandwidths.
This pin is for bypassing the LDO to ground with a capacitor.
Along with CLK, this is the differential input for the clock distribution section.
Along with CLK, this is the differential input for the clock distribution section.
