CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
Note 1: When power steering is enabled, the charge pump must be 4.5 V maximum.
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

Auxiliary charge pump supply, 3 to 5 V. Removing power safely powers down the associated divider chain
and charge pump.
Auxiliary charge pump output. The gain of the auxiliary charge pump phase detector is controlled by the
Phase Detector/Charge Pump Control Register.
Auxiliary charge pump ground.
Auxiliary VCO complimentary differential input.
Auxiliary VCO differential input.
ECL/CML, 3 V. Removing power safely powers down the associated divider chain and charge pump.
Digital ground.
Digital 3 V.
Serial address and data input pin. Address bits are followed by data bits.
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.
