LMX5453
Micro-Module Integrated Bluetooth®2.0 Baseband
Controller and Radio
1.0 General Description
2.0 New Features
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 in the on-chip ROM supports a com-
plete Bluetooth Link Manager and HCI with communication
through a UART or USB interface. This firmware features
point-to-point and point-to-multipoint link management, sup-
porting 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 IQ-
modulation with Gaussian-filtered bit-stream data, a voltage-
controlled oscillator (VCO) buffer, and a power amplifier.
The LMX5453 module is lead free and RoHS (Restriction of
Hazardous Substances) compliant. For more information on
those quality standards, please visit our green compliance
website at http://www.national.com/quality/green/
