with VCO and Synthesizer
Differential Tank Input for High-Frequency Oscillator
LO Buffer Amplifier—active low
No Connection. Must be left open-circuit.
Mode Select. High selects CDMA mode; low selects FM
mode.
Internal VCO Output. Depending on setting of BD bit, LOOUT
is either the VCO frequency (twice the IF frequency) or one-
half the VCO frequency (equal to the IF frequency).
+2.7V to +5.5V Supply for Digital Circuits
Digital Ground
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
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 for Analog Circuits
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.
No Connection.
Differential Negative Input for FM signal. Bypass to GND for
single-ended operation.
Standby Input—active low. Low powers down VGA and demod-
ulator while keeping VCO, PLL, and serial bus on.
Bypass Node. Must be capacitively decoupled (bypassed) to
analog V
