Minimalist wireless modems are now a reality
The miniature wireless modem end-product is now a reality, says CML Microcircuits, using its time, space and component-saving wireless data IC, the CMX990.
Suited to a variety of M2M applications, from vending machines to utility meters and alarm panels, the CMX990 easily replaces CML's existing GMSK packet-data modem, the CMX909B IC, to give unparalleled performance in next generation products operating on both Mobitex and nonMobitex networks.
The CMX990 offers a data range of 4 to 16Kbits/s with selectable BT values, at RF frequencies of 400MHz to 1GHz.
The CMX990 is configurable to both free-format and packet data schemes, is fully Mobitex compatible and can be set to comply with EN 300 113 and FCC CFR 47 Part 90 standards, employing simple task-command configuration to provide simplicity and efficiency to the control and operation of the modem.
FEC, CRC, data scrambling and interleaving functions are available on the CMX990.
Automatic Rx clock extraction and signal level measurement/compensation allows the unit to operate in all signal conditions.
By employing external VCO inputs, the two programmable on-chip synthesisers provide all the frequencies necessary for wireless data operation.
Addressable on-chip DACs and ADCs are provided for control and monitoring of a wide range of external functions, including system levels and the VCO loops, with separate dedicated functions for RF PA stage and TCXO control.
With low operational power of 3.0V and availability in a 'no-leads' 64 VQFN package, optimum power consumption can be assured at all times by the separate dynamic power saving of unused functions.
