1.0 Functional Description
Note 8: The timeout counter decrements after each phase detector comparison cycle.
1.4 SERIAL DATA INPUT TIMING
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 V
amplitudes of 1.84V
1.5 PHASE COMPARATOR AND INTERNAL CHARGE PUMP CHARACTERISTICS
Notes: Phase difference detection range: −2π to +2π
The Phase Detector Polarity F[6] = HIGH
The minimum width pump up and pump down current pulses occur at the ICP
