LMX5453 - National Semiconductor

LMX5453 Micro-Module Integrated Bluetooth 2.0 Baseband Controller and Radio

The LMX5453 is a highly integrated Bluetooth 2.0 compliant solution. The integrated baseband controller and 2.4 GHz radio combine to form a complete, small form-factor (6.1 mm x 9.1 mm x 1.2 mm) Bluetooth node. The on-chip memory, ROM, and Patch RAM provide lowest cost and minimize design risk with the flexibility of firmware upgrades. The firmware supplied .

Features

point-to-point and point-to-multipoint link management, supporting data rates up to 723 kbps. The radio employs an integrated antenna filter and switch to minimize the number of external components. The radio has a heterodyne receiver architecture with a low intermediate frequency (IF), which enables the IF filters to be integrated on-chip. The transmitter uses direct IQmodulation with Gaussian-filtered bit-stream data, a voltagecontrolled oscillator (VCO) buffer, and a power amplifier. The LMX5453 module is lead free and RoHS (Restriction of Hazardous Substances) compliant. For more informati.
