Wireless Data

The CMX7364 is a flexible high performance wireless data modem featuring a high level of integration, including RF ADCs and DACs as well as additional low power data converters for monitoring and control purposes.  At its heart a powerful DSP core is coupled to optimised hardware accelerators to provide efficient, low power implementation of data modem functionality, principally PHY and MAC layers.  The device supports a range of formatted data modes as well as a raw mode that allows users to freely develop their own link protocols.  The formatted data models include optimised forward error correction and pilot symbol insertion where appropriate.

The CMX7364 provides a range of flexible digital interfaces to allow easy interfacing with microcontrollers and a pass through interface for control of RF circuits.  The internal filters support channel bandwidths from 6.25 to 50 kHz enabling over air data rates of up to 40 ksamples/s.

The design is capable of interfacing to different radio architectures but is ideally matched to CML’s CMX994 family of  direct conversion receivers and CMX998 I/Q modulator with Cartesian linearization and built-in support for these devices via appropriate Function Images includes DC offset correction and AGC control.

The CMX7364 operates from a single 3.3V supply voltage and is available in a 64VQFN package.

Functionality of the CMX7364 is determined by loading a Function Image™ supplied by CML. The Function Image™ is downloaded on power up and configures the device for the required modulation scheme and associated parameters.

Devices are available through our Distributor Network.
