Bandwidth Selection Bit 0 (Digital Input): Sets the desired demodulator filter bandwidth. See
Table 1. Internally pulled-up to VDD.
Antenna (Input): High-impedance, internally AC-coupled receiver input. Connect this pin to the
matching network. See “Applications Information” for optional band-pass filter information.
Positive Supply Input: Connect a low ESL, low ESR decoupling capacitor from this pin to VSS,
as short as possible.
Data Slicing Threshold Capacitor (External Component): Capacitor extracts the DC average
value from the demodulated waveform which becomes the reference for the internal data slicing
comparator. See “Applications Information” for selection.
Data Output (Output): CMOS-level compatible data output signal.
Negative Supply Input: Connect this pin to the RF ground.
AGC Capacitor (External Component): Integrating capacitor for on-chip AGC (automatic gain
control). The decay/attack time-constant (τ) ratio is nominally 10:1. See “Applications
Information” for capacitor selection.
Reference Oscillator (External Component or Input): Timing reference for on-chip tuning and
alignment. Connect either a ceramic resonator or a crystal between this pin and VSS, or drive
the input with an AC-coupled 0.5VPP input clock.
