Description
Reference clock input.
Reference clock input.
Chooses reference between SYNC (0) & SYNC (1). (Refer to functional block diagram).
Selects between ÷1 and ÷2 frequency options. (Refer to functional block diagram).
Feedback input to phase detector.
Input for external loop filter connection.
Clock output.
Inverted clock output.
Clock output (2 x Q frequency).
Clock output (Q frequency ÷ 2).
Indicates phase lock has been achieved (HIGH when locked).
Asynchronous reset (active LOW) and output enable (active HIGH). When HIGH, outputs are
enabled. When LOW, outputs are in HIGH impedance.
Disables phase-lock for low frequency testing. (Refer to functional block diagram).
