The CMX7164 provides 4/16/64-QAM and root-raised-cosine 2/4FSK baseband modem functions in a single chip, replacing the current need for user-programmed DSP plus codec ICs.
This development includes digital IF filters, auxiliary codecs, clock generator and I/O functions.
The device is a complete baseband modem system delivering high performance and high spectral efficiency for narrowband applications. These include M2M systems over dedicated channels, digital software-defined radio, high-speed wireless data and SCADA systems. The device is also compliant with ETSI, FCC and ARIB standards around the world.
Features include: 2/4FSK up to 20 Kbps in 25 kHz; QAM up to 96 Kbps in 25 kHz; maintains over air compatibility with the FX919B/MX919B and CMX7143 industry standard modems; 3.3 V supply; selectable power-saving modes; selectable modulation, symbol rate and FEC; built on CML’s FirmASIC component technology; available in (Q1) 64-pin VQFN and (L9) 64-pin LQFP packages.
