Offering a data range of 4 to 16kbit/s with selectable BT values, at RF frequencies of 400MHz to 1GHz, the CMX990 is formattable to both freeformat 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.
FEC, CRC, data scrambling and interleaving functions are available. Automatic Rx clock extraction and signal level measurement and compensation allow the CMX990 modem to operate in all signal conditions.
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 available 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.
The 3V device is available in a 64 VQFN package.
