ML7050LA
Bluetooth RF Transceiver IC
1/16
GENERAL DESCRIPTION
The Oki ML7050LA is a highly integrated Bluetooth
TM
radio transceiver designed to operate in the global 2.4 GHz
Industrial, Scientific, and Medical (ISM) band. The ML7050LA architecture incorporates vital intermediate frequency
(IF) and radio frequency (RF) circuits on a low cost, integration-friendly bulk CMOS process.
Bluetooth technology directly supports short range, wireless voice and data communications with 1 Mbps throughput
performance in the public ISM band across many applications, employing rapid frequency hopping (1.6K hops/s)
spread spectrum (FHSS) approach. The ML7050LA highly integrated CMOS Bluetooth RF transceiver LSI will
establish a 2.4 to 2.5 GHz communication link compliant with Bluetooth Specification Version 1.1 and is packaged in
the Oki 48-pin ball grid array (BGA) package requires only 7 mm x 7 mm of the systems critical board space.
Oki's Bluetooth LSI family includes baseband LSI (ML70511LA), System Development Kit (BT-SDK), firmware and
software (BTS Pack1/2/3). Together, the RF LSI (ML7050LA) and baseband (ML70511LA) devices form a complete
hardware solution optimized for low system cost, small form factor, and reduced power consumption Bluetooth
applications.
FEATURES
Circuit design based on the Bluetooth Specification Version 1.1.
CMOS process technology lowers system cost and simplifies future baseband integration
Fully integrated CMOS RF LSI: TX/RX switch, power amplifier, LNA, image rejection mixer, VCO, PLL, gm-
C IF filter, modulator, and demodulator.
Low IF circuitry eliminates off-chip SAW filter reducing bill-of-material (BOM)
Class 2 power operation compliant covering a wide range of applications
Seamless interface with Oki's ML70511LA Bluetooth baseband controller LSI
Power supply voltage: 2.7 to 3.3 V
Package: 48-pin BGA (7 mm x 7 mm x 1.41mm)
