Pin #
Pin Name
Type
Description
17
GNDxtal
Power and ground
Crystal oscillator ground.
18
LD/PSaux
Analog output
Programmable output pin. Indicates auxiliary phase detector out-of-lock as an active low pulsing open
collector output (high impedance when lock is detected), or helps the loop filter steer the auxiliary VCO.
This pin is configured using the Phase Detector/Charge Pumps Control Register.
19
VCCcp_aux (Note 1)
Power and ground
Auxiliary charge pump supply, 3 to 5 V. Removing power safely powers down the associated divider chain
and charge pump.
20
CPout_aux
Analog output
Auxiliary charge pump output. The gain of the auxiliary charge pump phase detector is controlled by the
Phase Detector/Charge Pumps Control Register.
21
GNDcp_aux (Note 1)
Power and ground
Auxiliary charge pump ground.
22
Fvco_aux
Input
Auxiliary VCO complimentary differential input.
23
Fvco_aux
Input
Auxiliary VCO differential input.
24
VCCcml_aux
(Note 1)
Power and ground
ECL/CML, 3 V. Removing power safely powers down the associated divider chain and charge pump.
25
GNDdigital (Note 1)
Power and ground
Digital ground.
26
VCCdigital (Note 1)
Power and ground
Digital 3 V.
27
Data
Digital input
Serial address and data input pin. Address bits are followed by data bits.
28
CS
Digital input
Active low enable pin. Enables loading of address and data on the Data pin on the rising edge of Clock.
When CS goes high, data is transferred to the register indicated by the address. Subsequent clock edges
are ignored.
Note 1: Associated pairs of power and ground pins must be decoupled using 0.1 F capacitors.

Note:
Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal values. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This
device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human
body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
