Texas Instruments Designs New HD Radio Chipsets

Texas Instruments has designed two new chipsets for HD Radio.
“Depending on their design approach, designers can choose either of the new digital basebands for building an HD Radio receiver,” said TI Marketing Manager John Gardner.
The new digital basebands integrate TI’s expertise in DSP technology and software by Ibiquity Digital, with all of the digital functions required to build an AM/FM and HD Radio receiver, in addition to audio post processing and MP3 and Windows Media Audio CD support.
The new TMS320DRI350 combines IF-sampled AM / FM and HD Radio processing on the same chip. In addition, TI is responding to manufacturers’ demand for an HD Radio-only solution with its new TMS320DRI300 baseband, providing HD Radio functionality, while allowing OEMs to continue using their own proprietary designs for AM/FM support.
According to TI, the DRI300 allows manufacturers to build on existing solutions and add digital radio capabilities.
Samples of TI’s DRI350 and DRI300 HD Radio basebands are available now with volume production expected in Q4.
