Pin Function
Reference resonator input connection to Colpitts oscillator stage. May also be driven by external reference
signal of 1.5V p-p amplitude maximum.
Negative supply connection associated with ANT RF input.
RF signal input from antenna. Internally AC coupled. It is recommended that a matching network with an
inductor -to-RF ground is used to improve ESD protection.
Negative supply connection associated with ANT RF input.
Positive supply connection for all chip functions.
Squelch control logic input with an active internal pull-up when not shut down.
Logic control input with active internal pull-up. Used in conjunction with SEL1 to control the demodulator low
pass filter bandwidth. (See filter table for SEL0 and SEL1 in application section)
Shutdown logic control input. Active internal pull-up.
Logic control input with active internal pull-up. Used in conjunction with SEL0 to control the demodulator low
pass filter bandwidth. (See filter table for SEL0 and SEL1 in application section)
Demodulation threshold voltage integration capacitor connection. Tie an external capacitor across CTH pin
and GND to set the settling time for the demodulation data slicing level. Values above 1nF are
recommended and should be optimized for data rate and data profile.
AGC filter capacitor connection. CAGC capacitor, normally greater than 0.47µF, is connected from this pin to
GND
Received signal strength indication output. Output is from a buffer with 200Ω typical output impedance.
Reference resonator input connection to Colpitts oscillator stage, 7pF, in parallel with low resistance MOS
switch-to-GND, during normal operation. Driven by startup excitation circuit during the internal startup control
sequence.
Negative supply connection for all chip functions except RF input.
Demodulated data output.
Not Connected (Connect to Ground)
