Pin Name
Bandwidth Selection Bit 0 (Digital Input): Used in conjunction with SEL1 to set
the desired demodulator filter bandwidth. See Table 1. Internally pulled-up to
VDDRF.
RF Power Supply: Ground return to the RF section power supply.
Antenna (Analog Input): For optimal performance the ANT pin should be
impedance matched to the antenna. See “Applications Information” for
information on input impedance and matching techniques.
RF Power Supply: Positive supply input for the RF section of the IC.
Base-Band Power Supply: Positive supply input for the baseband section
(digital section) of the IC.
Data Slicing Threshold Capacitor (Analog I/O): Capacitor connected to this
pin extracts the dc average value from the demodulated waveform which
becomes the reference for the internal data slicing comparator.
Not internally connected
Base-Band Power Supply: Ground return to the baseband section power
supply.
Data Output (Digital Output)
Shutdown (Digital Input): Shutdown-mode logic-level control input. Pull low to
enable the receiver. Internally pulled-up to VDDRF.
Wakeup (Digital Output): Active-low output that indicates detection of an
incoming RF signal.
Automatic Gain Control (Analog I/O): Connect an external capacitor to set the
attack/decay rate of the on-chip automatic gain control.
Bandwidth Selection Bit 1 (Digital Input): Used in conjunction with SEL0 to set
the desired demodulator filter bandwidth. See Table 1. Internally pulled-up to
VDDRF.
Reference Oscillator: Timing reference, sets the RF receive frequency.
Sweep-Mode Enable (Digital Input): Sweep- or Fixed-mode operation control
input. SWEN high= sweep mode; SWEN low = conventional superheterodyne
receiver. Internally pulled-up to VDDRF.
