LMX5453

Micro-Module Integrated Bluetooth

Controller and Radio

1.0 General Description

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
