Obsolete product - Not for new designs.
The MLX73290-M is a 299 to 960MHz multi-channel transceiver chip. The IC is designed for general purpose applications for example in the European bands at 433MHz and 868MHz or for similar applications in North America or Asia, e.g. at 315MHz or 915MHz. It is also well-suited for narrow-band applications which meet the ARIB standard STD-T67 in the frequency range 426MHz to 470MHz.
The output power, frequency channel, modulation type and frequency deviation are programmable via the serial programming interface (SPI). The synthesizer operates with a fractional-N PLL and VCO with integrated inductor.
The high frequency resolution of the MLX73290-M and its PLL phase noise performance facilitate it for narrow-band applications. There are six selectable modulation schemes: on-off keying (OOK), binary frequency shift keying (FSK), minimum shift keying (MSK) as well as their Gaussian filtered versions (GFSK, GMSK, GOOK).
The low-IF receiver part comprises fully digital demodulation and self-polling features together with channel scanning and packet recognition.
