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 × 9.1 mm × 1.2
mm) Bluetooth node.
The baseband controller has a standard Host
Controller Interface (HCI). Based on the Texas
Instruments 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.
The firmware supplied in the on-chip ROM supports a
complete 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, 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 IQ-modulation with Gaussian-filtered bit-
stream data, a voltage-controlled oscillator (VCO)
buffer, and a power amplifier.
