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 × 9.1
mm × 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 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.
The LMX5453 module is lead free and RoHS (Restriction of Hazardous Substances) compliant.
