Pin Function
Demodulation Threshold Voltage Integration Capacitor. Connect a 0.1μF capacitor from CTH pin to GND
to provide a stable slicing threshold.
AGC Filter Capacitor. Connect a capacitor from this pin to GND. Refer to the AGC Loop and CAGC
section for information on the capacitor value.
Received Signal Strength Indicator. The voltage on this pin is an inversed amplified version of the voltage
on CAGC. Output is from a switched capacitor integrating op amp with 250Ω typical output impedance.
Programming clock input.
Reference resonator connection to the Pierce oscillator. Internal capacitance of 7pF to GND during normal
operation.
