ML7050LA

Bluetooth RF Transceiver IC

GENERAL DESCRIPTION

The Oki ML7050LA is a highly integrated BluetoothTM radio transceiver designed to operate in the global 2.4 GHz
Industrial, Scientific, and Medical (ISM) ban d. The ML 7050LA archi tecture incorporates v ital intermedi ate f requency
(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 L SI family includes bas eband LSI (ML 70511LA ), Sys tem Developm ent Kit (BT-SD K), fi rmware an d
software (BTS Pack1/2/3). Togeth er, th e RF LSI (ML7050L A) and baseban d (ML70511L A) dev ices f orm a compl ete
hardware solution optimized for low system cost, small form factor, and reduced power consumption Bluetooth
applications.
