In the last several years, as car audio continues developing into a multi-functional, multimedia technology, manufacturers have increasingly been called upon to achieve sophisticated, highly integrated system design and cost reduction in theproduct planning stage.With the demand for greater integration as the backdrop, Fujitsu Ten has been moving to combine the various functions of circuits components of car audio products -- into IC chips. In one area, our car radio tuner R&D effort, the major challenge has beendevelopment of an IC that can bring multiple functions together on a more compact, cost-effective chip than the conventional tuner IC.Capitalizing on Fujitsu Ten design expertise, we have recently developed such a multi-function tuner IC. Equipped with a keyless entry reception function, the new IC is an added feature to the Fujitsu Ten car radio tuner, which already includes suchperipheral functions as FM diversity reception and an AM noise canceller.
