Product Preview CMX7364Multi-mode High Performance Wireless Data Modem 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. Features • Modem PHY Rx and Tx data converters Programmable channel filters • Modem lower MAC AFSD FEC Packet build Pilot symbol insertion • C-BUS (SPI Compatible) Serial Interfaces • Auxiliary functions Low speed ADCs/DACs Power amplifier Ramp DAC Programmable clock generator • Power management Integrated core LDO Automatic clock gating • Diagnostic functions Applications • VHF/UHF modems Telemetry SCADA RTK • Satellite modems • Custom ISM radios 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. 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. The CMX7364 operates from a single 3.3V supply voltage and is available in a 64VQFN package.
