• Stereo Headsets
• Personal Digital Assistants
• Personal Computers
• Automotive Telematics
• Better than -80 dBm input sensitivity
• Class 2 operation
• Low power consumption:
• Accepts external clock or crystal input:
– Clocking option 12/13 MHz with PLL bypass
mode for power reduction
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 × 9.1 mm × 1.2
mm) Bluetooth node.
– 10-20 MHz external clock or crystal network
– Secondary 32.768 kHz oscillator for low-
power modes
– Advanced power management features
• High integration:
– Implemented in 0.18 μm CMOS technology
– RF includes on-chip antenna filter and
switch
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.
• On-chip firmware with complete HCI
• Embedded ROM (200K) and Patch RAM (16.6K)
memory
• Up to 7 Asynchronous Connection Less (ACL)
links
• Support for two simultaneous voice or
Extended Synchronous Connection Oriented
(eSCO) and Synchronous Connection Oriented
(SCO) and links.
• Enhanced scatternet
• Interlaced scan
• Flushing
• Audio PCM slave mode support
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
