Reference clock input
Reference clock input
Chooses reference between sync[0] & Sync[1]
Selects Q output frequency
Feedback input to phase detector
Input for external RC network
Clock output (locked to sync)
Inverse of clock output
2 x clock output (Q) frequency (synchronous)
Clock output(Q) frequency 2 (synchronous)
Indicates phase lock has been achieved (high when locked)
Asynchronous reset (active low)
Disables phase–lock for low freq. testing
Power and ground pins (note pins 8, 10 are
“quiet” supply pins for internal logic only)
