All Sleep. All receive circuits powered down, supply current <10 µA.
Digital Receive. First IF mixing stage, AGC amp and I/Q quadrature
demodulators active.
Analog/FM Receive. First IF mixing stage, 40 dB IF amp, 60 dB limiting amp,
RSSI, and FM detector active.
All Active. All receive circuits functional, e.g., digital mode I & Q demodulator
used with analog RSSI.
Enable Digital Mode. Positive logic enable connection for digital mode operation.
Enable Analog Mode. Positive logic enable connection for analog mode
operation.
Q Output. Differential output from Q mixer of quadrature demodulator.
Q Output (Inverting). Differential output from Q mixer of quadrature demodulator.
Clock Input. Local oscillator (clock) input to quadrature demodulator phase shifter;
to be capacitively coupled. Input frequency must be four times second IF center
frequency.
I Output (Inverting). Differential output from I mixer of quadrature demodulator.
I Output. Differential output from I mixer of quadrature demodulator.
Automatic Gain Control. AGC control input; to be connected to dc source of
0.25 V—1.55 V.
Common-Mode Voltage. Common-mode voltage dc offset set point for I & Q
interface, typically V
Digital Signal Ground. Signal ground for digital section limiting amplifier; connect
to ground with 0.1 µF capacitor.
Digital Second IF Input. Differential input to digital section AGC amplifier; to be
directly coupled to dielectric sources such as ceramic filters. Pin 30 is
approximately 2 k
Digital Second IF Input (Inverting). Differential input to digital section AGC
amplifier. To be ac-grounded.
Second IF Ground. Power supply ground for both analog and digital second IF
amplifier and demodulator sections.
