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 LMX5453 is a drop in replacement for the LMX5452.

The LMX5453 has new features added:

•

eSCO

eSCO over USB HCI transport

Enhanced scatternet

Interlaced scan

The on-chip memory, ROM, and Patch RAM provide lowest

cost and minimize design risk with the flexibility of firmware

upgrades.

Flushing

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.

Audio PCM slave mode support

Generic PCM configuration

3.0 Applications

The radio employs an integrated antenna filter and switch to

minimize the number of external components.

•

Mobile Handsets

USB Dongles

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.

Stereo Headsets

Personal Digital Assistants

Personal Computers

Automotive Telematics

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/
