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- or continuos message mode using a special protocol to ensure high reliability even in presence of strong pulsed interferers in close adjacent bands like e.g. GSM.

Featuer

· 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.
