Pin type
Power (A) Power supply (3 V) for analog modules (mixer and IF)
Ground (A) Ground connection (0 V) for analog modules (mixer and IF)
RF Input RF signal input from antenna
RF output RF signal output to antenna
Power (A) Power supply (3 V) for analog modules (LNA and PA)
Ground (A) Ground connection (0 V) for analog modules (LNA and PA)
Ground (A) Ground connection (0 V) for analog modules (PA)
Ground (A) Ground connection (0 V) for analog modules (VCO and prescaler)
Power (A) Power supply (3 V) for analog modules (VCO and prescaler)
Analog input Connection no 1 for external VCO tank inductor
Analog input Connection no 2 for external VCO tank inductor
Analog output Charge pump current output
The pin can also be used as PLL Lock indicator. Output is high
when PLL is in lock.
Connection for external precision bias resistor (82 kΩ, ± 1%)
Analog output
Ground (A) Ground connection (0 V) for analog modules (backplane)
Power (A) Power supply (3 V) for analog modules (general)
Ground (A) Ground connection (0 V) for analog modules (general)
Analog output Crystal, pin 2
Analog input Crystal, pin 1, or external clock input
Ground (A) Ground connection (0 V) for analog modules (guard)
Ground (D) Ground connection (0 V) for digital modules (substrate)
Power (D) Power supply (3 V) for digital modules
Ground (D) Ground connection (0 V) for digital modules
Digital Data input/output. Data input in transmit mode. Data output in
input/output receive mode
Digital output Data clock for data in both receive and transmit mode
Digital input Programming clock for 3-wire bus
Digital Programming data for 3-wire bus. Programming data input for
input/output write operation, programming data output for read operation
Digital input Programming address latch enable for 3-wire bus. Internal pull-up.
Analog output The pin can be used as RSSI or 10.7 MHz IF output to optional
external IF and demodulator. If not used, the pin should be left
open (not connected).
