ASCELL3912

ASCell3912 ISM 868 MHz, 433 MHz and 315 MHz FSK Receiver Cell Preliminary Data Sheet ISM 868 MHz, 433 MHz and 315 MHz FSK Receiver Cell – Preliminary Data Sheet ASCell3912 Austria Mikro Systeme International AG Key Features Supports triple band operation: Europe 868 MHz and 433 MHz-, US and Japan 315 MHz ISM band. Designed to be conform to EN 300 220, and FCC 47 CFR Ch.1 par.15 requirements. Provides highly reliable packet oriented data transmission in blocks of 128 bit. Event oriented single message transmission and status oriented and continuous message transmission supported. Special transmission protocol for high reliability even in presence of burst interferer (e.g. GSM) implemented. RX sensitivity of the receiver typical -100 dBm. Supports clock for an external µC and allows clock free total shut down of the whole system. Wide supply range between 2.7 to 5.5 V. Low RX current, typical 10 mA @ 2.4 V. Low idle mode current, typical 1.2mA. Wide operating temperature range from –40 °C to +85 °C. Only a low cost XTAL for 25 ppm (868 MHz) or 50 ppm (433 and 315 MHz) reference frequency tolerance required. Minimum only 1 XTAL and 4 capacitors externally required. General Description The ASCell3912 is a low power, triple ISM band (868 / 433 / 315 MHz), single channel FSK receiver designed to work in a remote control link together with the SC3911 transmitter system cell. The ASCell3912 performs packet oriented data transmission, in a single message-...
