FUNCTION

RF Output. This pin is AC coupled and should be connected to a non-reflective 50 ohm load.

Supply Input. Decoupling capacitors to the ground plane should be placed as close as possi-

ble to this pin. Use an ultra low-noise regulator followed by an RC filter for best noise.

Supply Input. Decoupling capacitors to the ground plane should be placed as close as possi-

ble to this pin. Use an ultra low-noise regulator followed by an RC filter for best noise.

Reference Input. This is a CMOS input with a nominal threshold of V2/2 and a dc equivalent

input resistance of 100K ohms. This input can be driven from a CMOS or TTL crystal clock

oscillator or it can be ac coupled.

Analog and RF Ground.

Serial Interface. This input functions as CS in MICROWIRE/SPI Bus mode. This input func-

tions as SDA in I2C BUS mode.

Serial Interface. This input functions as DATA in MICROWIRE/SPI BUS mode. This input

functions as SCL in I2C BUS mode.

Serial Interface. This input functions as CLOCK in MICROWIRE/SPI BUS mode. This input

must be connected to the DIGITAL GROUND in I2C BUS mode.

Lock Detect. This output is active high and provides a continuous digital lock status.

CAUTION!

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as

4000V readily accumulate on the human body and test equipment and can dis-

charge without detection. Although the PNP family of synthesizers feature ESD

protection circuitry, permanent damage may occur on devices subjected to high-

energy electrostatic discharges. Therefore, proper ESD precautions are recom-

mended to avoid performance degradation or loss of functionality
