Multi-mode wireless data modem supports GMSK/GFSK
The incorporation of FirmASIC technology allows the product’s function and feature set to be easily configured via special Function Image™ data files. These are uploaded during device initialisation, either automatically from an external serial memory or via a host microcontroller over the built-in C-BUS serial interface.
The 7164FI-1.x supports GMSK/GFSK modulation with BT = 0.5, 0.3, 0.27 or 0.25 and up to 20 kbps, zero IF (I/Q) Rx and two-point modulation or I/Q modulation Tx. Flexible bit rates support a wide range of applications requiring a selectable flexible bit rate and robustness. The GMSK/GFSK data is over-air compatible with the FX/MX909B and the CMX7143FI-1.x.
The CMX7164 is a complete baseband modem system providing 4/16/64-QAM, root raised cosine 2/4 level FSK and GMSK/GFSK baseband modem functions in a single chip. The device provides multiple modulations for narrowband applications including M2M systems over dedicated channels, digital software defined radio (SDR), high-speed wireless data and SCADA systems. The half-duplex device operates up to 96 kbps in 25 kHz and it supports 6.25 kHz, 12.5 kHz and 25 kHz bandwidths, making it ideal for narrow banding migration worldwide.
The CMX7164 is available now and operates from a 3.3 V supply and includes selectable power saving modes. It is available in 64-VQFN and 64-LQFP packages.
