Pin Function
Demodulated data output.
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
subsection)
Demodulation threshold voltage integration capacitor. Capacitor to GND sets 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. A capacitor, normally greater than 0.47uF, is connected from this pin to GND
Received signal strength indication output. Output is from a buffer with 200 ohms typical output
impedance.
Not Connected
Reference resonator connection. 7pF in parallel with low resistance MOS switch to GND during
normal operation. Driven by startup excitation circuit during the internal startup control sequence.
