Pin Function
Reference resonator connection to the Pierce oscillator. May also be driven by external reference signal of
200mVp-p to 1.5V p-p amplitude maximum. Internal capacitance of 7pF to GND during normal operation.
Ground connection for ANT RF input. Connect to PCB ground plane.
Antenna Input: RF Signal Input from Antenna. Internally AC coupled. It is recommended to use a matching
network with an inductor to RF ground to improve ESD protection.
Ground connection for ANT RF input. Connect to PCB ground plane.
Positive supply connection for all chip functions. Bypass with 0.1 μ F capacitor located as close to the VDD
pin as possible.
Squelch Control Logic-Level Input. An internal pull-up (5 μ A typical) pulls the logic-input HIGH when the
device is enabled. A logic LOW on SQ squelches, or reduces, the random activity on DO pin when there is
no RF input signal.
Tie this pin to VDD to ensure robust register programming. Use register bits D[4:3] to set demodulation
bandwidth.
Shutdown Control Logic-Level Input. A logic-level LOW enables the device. A logic-level HIGH places the
device in low-power shutdown mode. An internal pull-up (5 μ A typical) pulls the logic input HIGH. To ensure
that the part starts up correctly, connect a 1 μ F capacitor from VDD to SHDN, and a 50k ? resistor from
SHDN pin to GND. After the supply voltage settles, apply a HIGH logic level voltage to SHDN to turn the
part off, then a LOW logic level voltage to turn the part on before programming or operating the device.
Ground connection for all chip functions except for RF input. Connect to PCB ground plane.
Data Output. Demodulated data output. A current limited CMOS output during normal operation, 25k ? pull-
down is present when device is in shutdown.
Tie this pin to VDD to ensure robust register programming. Use register bits D[4:3] to set demodulation
bandwidth.
