8 Detailed Description
The AS3930 is a one-dimensional low power low-frequency wake-up receiver. The AS3930 is capable of detecting the presence of an inductive
coupled carrier and extract the envelope of the On-Off-Keying (OOK) modulated carrier. In case the carrier is Manchester coded, then the clock
is recovered from the transmitted signal and the data can be correlated with a programmed pattern. If the detected pattern corresponds to the
stored one, then a wake-up signal (IRQ) is risen up. The pattern correlation can be bypassed in which case the wake-up detection is based only
on the frequency detection.
The AS3930 is made up of a single receiving channel, one envelop detector, one data correlator, 8 programmable registers with the main logic
and a real time clock.
The digital logic can be accessed by an SDI. The real time clock can be based on a crystal oscillator or on an internal RC. If the internal RC
oscillator is used, a calibration procedure can be performed to improve its accuracy.
