LMX5452 - Micro-Module Integrated Bluetooth 1.2 Baseband Controller and Radio

Description

The LMX5452 is a highly integrated Bluetooth 1.2 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 baseband controller has a standard Host Controller Interface (HCI).

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 LMX5.

LMX5452 Micro-Module Integrated Bluetooth 1.2 Baseband Controller and Radio February 2006 LMX5452 Micro-Module Integrated Bluetooth ® 1.2 Baseband Controller and Radio 1.0 General Description The LMX5452 is a highly integrated Bluetooth 1.2 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 baseband controller has a standard Host Controller Interface (HCI). Based on the National Semiconductor CompactRISCTM 16-bit processor, the LMX5452 is optimized to handle the audio, data, and link management processing requirements of a Bluetooth node. The on-chip memory, ROM, and Patch RAM provide lowest cost and minimize design risk with the flexibility of firmware upgrades.
