FUNCTION
Differential Tank Input for Low-Frequency Oscillator
No Connection. Must be left open-circuit.
Differential Tank Input for High-Frequency Oscillator
LO Buffer Amplifier—active low
Mode Select. High selects CDMA mode; low selects FM mode.
Internal VCO Output. Depending on setting of BD bit, LOOUT is

Reference Frequency Input
Shutdown Input—active low. Low powers down entire device,
including registers and serial interface.
Differential In-Phase Baseband Output, or FM signal output if FM_I
mode is selected.
Lock Output—open-collector pin. Logic high indicates phase-locked
condition.
Differential Quadrature-Phase Baseband Output. Disabled if FM_I
mode is selected.
Clock input of the 3-wire serial bus
Enable Input. When low, input shift register is enabled.
Data input of the 3-wire serial bus.
+2.7V to +5.5V Supply
VGA Gain Control Input. Control voltage range is 0.5V to 2.3V.
Differential CDMA Input. Active in CDMA mode.
Differential Positive Input. Active in FM mode.
Differential Negative Input for FM signal. Bypass to GND for
single-ended operation.
Standby Input—active low. Low powers down VGA and demodulator
while keeping VCO, PLL, and serial bus on.
Bypass Node. Must be capacitively decoupled (bypassed) to pin 17.
