Pin Descriptions
PNP-850-L22
Mnemonic
FUNCTION
RF
RF Output. This pin is AC coupled and should be connected to a non-reflective 50 ohm load.
V1
Supply Input. Decoupling capacitors to the ground plane should be placed as close as possi-
ble to this pin.
V2
Supply Input. Decoupling capacitors to the ground plane should be placed as close as possi-
ble to this pin.
REF
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.
GND
Digital, Analog and RF Ground.
DA0
Serial Interface. This input functions as CS in MICROWIRE/SPI Bus mode. This input func-
tions as SDA in I2C BUS mode.
DA1
Serial Interface. This input functions as DATA in MICROWIRE/SPI BUS mode. This input
functions as SCL in I2C BUS mode.
DA2
Serial Interface. This input functions as CLOCK in MICROWIRE/SPI BUS mode. This input
must be connected to the GROUND in I2C BUS mode.
LD
Lock Detect. This output is active high and provides a continuous digital lock status.
Absolute Maximum Ratings

REF IN to Ground
-0.3 to Dvdd + 0.3 Vdc
RF OUT to Ground
+/- 25 Vdc
Digital I/O to Ground
-0.3 to V2 + 0.3 Vdc
Operating Temperature
-40
° to +85°C
Storage Temperature
-55
° to +100°C
Stress above those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. This is a stress
rating only. Operation of the device above the conditions listed
in the operational sections of this specification is not implied.

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
