Description
Reference Monitor (Output). This pin has multiple selectable outputs; see Table 44,
Register 0x1B.
Lock Detect (Output). This pin has multiple selectable outputs; see Table 44,
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 44, Register 0x17.
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 loop bandwidths.
This pin is for bypassing the LDO to ground with a capacitor.
3.3 V Power Pins.
Along with CLK, this is the self-biased differential input for the clock distribution section.
Along with CLK, this is the self-biased differential input for the clock distribution section.
