SPIRIT1QTR

IC, RF TRX, LOW POWER SUB1GHZ, QFN20.

The SPIRIT1QTR is a very low-power RF Transceiver IC. It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868 and 915MHz, but can also be programmed to operate at other additional frequencies in the 300 to 348MHz, 387 to 470MHz and 779 to 956MHz bands. The air data rate is programmable from 1 to 500kbps and the SPIRIT1 can be used in systems with channel spacing of 12.5/25kHz, complying with the EN 300 220 standard. It uses a very small number of discrete external components and integrates a configurable baseband modem, which supports data management, modulation and demodulation. The data management handles the data in the proprietary fully programmable packet format also allows the M-Bus standard compliance format (all performance classes). However, the SPIRIT1QTR can perform cyclic redundancy checks on the data as well as FEC encoding/decoding on the packets.
