Functional Description (Continued)
SERIAL DATA INPUT TIMING
PHASE COMPARATOR AND INTERNAL CHARGE PUMP CHARACTERISTICS
DS101367-9
Parenthesis data indicates programmable reference divider data.
Data shifted into register on clock rising edge.
Data is shifted in MSB first.
tCS = Data to Clock Set Up Time
tCH = Data to Clock Hold Time
tCWH = Clock Pulse Width High
tCWL = Clock Pulse Width Low
tES = Clock to Load Enable Set Up Time
tEW = Load Enable Pulse Width
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.
DS101367-10
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.
