DESCRIPTION: THE AS3930A IS A SINGLECHANNEL LOW POWER ASK RECEIVER THAT IS ABLE TO GENERATE A WAKEUP UPON DETECTION OF A DATA SIGNAL WHICH USES A LF CARRIER FREQUENCY BETWEEN 110 150 KHZ. THE INTEGRATED CORRELATOR CAN BE USED FOR DETECTION OF A PROGRAMMABLE 16BIT WAKEUP PATTERN. THE AS3930A PROVIDES A DIGITAL RSSI VALUE, IT SUPPORTS A PROGRAMMABLE DATA RATE. THE AS3930A OFFERS A REALTIME CLOCK (RTC), WHICH IS EITHER DERIVED FROM A CRYSTAL OSCILLATOR OR THE INTERNAL RC OSCILLATOR. THE PROGRAMMABLE FEATURES OF AS3930A ENABLE TO OPTIMIZE ITS SETTINGS FOR ACHIEVING A LONGER DISTANCE RETAINING A RELIABLE WAKEUP GENERATION. THE SENSITIVITY LEVEL OF AS3930A CAN BE ADJUSTED IN PRESENCE OF A STRONG FIELD OR IN NOISY ENVIRONMENTS. THE DEVICE IS AVAILABLE IN A QFN 4X4 16 LD PACKAGE.   APPLICATIONS THE AS3930A IS IDEAL FOR ACTIVE RFID TAGS, REALTIME LOCATION SYSTEMS, OPERATOR IDENTIFICATION, ACCESS CONTROL, AND WIRELESS SENSORS.   KEY FEATURES SINGLE CHANNEL ASK WAKEUP RECEIVER CARRIER FREQUENCY RANGE 110 150 KHZ PROGRAMMABLE WAKEUP PATTERN (16BITS) DOUBLING OF WAKEUP PATTERN SUPPORTED WAKEUP WITHOUT PATTERN DETECTION SUPPORTED WAKEUP SENSITIVITY 100VRMS (TYP.)
