LMX5452中文资料Micro-Module Integrated Bluetooth 1.2 Baseband Controller and Radio数据手册TI规格书

描述 Description

The LMX5452 is a highly integrated1.2 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)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 anode.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 completeLink 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 LMX5452 module is lead free and RoHS (Restriction of Hazardous Substances) compliant.
