Pin Function
Ground Return (input): ground return to the power supply. See “Applications Information” for bypass
capacitor details.
Antenna (Input): See “Applications Information” for information on input impedance. For optimal
performance the antenna impedance should be matched to the antenna pin impedance.
Power Supply (Input): Positive Supply input for the RF IC. Connect a low ESL, low ESR decoupling
capacitor from this to VSS, with lead length kept 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.
Digital Output (Output): CMOS level compatible data output signal.
Shutdown (Input): Shutdown-mode logic-level control input. Pull low to enable the receiver. This input
is pulled-up internally to VDD.
AGC Capacitor (External Component): Integrating capacitor for on-chip AGC (automatic gain control).
See “Applications Information” for capacitor selection.
Reference Oscillator (External Component or Input): Timing reference for on-chip tuning and
alignment.
