ASCell3911 ISM 868 MHz, 433 MHz and 315 MHz FSK Transmitter Preliminary Data Sheet ISM 868 MHz, 433 MHz and 315 MHz FSK Transmitter – Preliminary Data Sheet ASCell3911 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. Supports clock for an external µC and allows clock free total shut down of the whole system. Wide supply range between 2,2 to 3,5 V. Low TX current, typical 8,5 mA @ 2,2 V. Low standby current, typical 0,5 µA. 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. Typically only 1 XTAL, 4 capacitors and 2 inductors externally required. General Description The ASCell3911 is a low power, triple ISM band (868 / 433 / 315 MHz), single channel FSK transmitter designed to work in a remote control link together with the SC3912 receiver system cell. The ASCell3911 performs packet oriented data transmission, in a single message- or continuosmessage mode using a specia...
