Functional Description (Continued)
PHASE DETECTOR POLARITY
Depending upon VCO characteristics, R16 bit should be set
accordingly: (see figure right)
When VCO characteristics are positive like (1), R16 should
be set HIGH;
When VCO characteristics are negative like (2), R16 should
be set LOW.

VCO Characteristics
DS012331-16
DS012331-17
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 2.2V @ VCC = 2.7V and 2.6V @ VCC = 5.5V.
DS012331-18
Notes: Phase difference detection range: 2
π to +2π
The minimum width pump up and pump down current pulses occur at the Do pin when the loop is locked.
R16 = HIGH
