Note 8: The timeout counter decrements after each phase detector comparison cycle.
1.4 SERIAL DATA INPUT TIMING
1.5 PHASE COMPARATOR AND INTERNAL CHARGE PUMP CHARACTERISTICS
DS100127-9
Notes: Parenthesis data indicates programmable reference divider data.
Data shifted into register on clock rising edge.
Data is shifted in MSB first.
TEST CONDITIONS: The Serial Data Input Timing is tested using a symmetrical waveform around VCC/2. The test waveform has an edge rate of 0.6V/ns with
amplitudes of 1.84V @ VCC = 2.3V and 4.4V @ VCC = 5.5V.
DS100127-10
Notes: Phase difference detection range: 2
π to +2π
The Phase Detector Polarity F[6] = HIGH
The minimum width pump up and pump down current pulses occur at the ICPo pin when the loop is locked.
