Single-chip solution enables low-cost handsets in emerging markets

Qualcomm's QSC1100 is a single-chip solution that enables CDMA2000 handsets that break new industry price barriers for emerging global markets. In addition to supporting features such as downloadable polyphonic ringtones and color displays, Qualcomm claims the part doubles talk time compared to currently available CDMA2000 handsets. In addition, it offers multiple technologies that could potentially improve network capacity by up to 100%.

The QSC1100 solution's integration of baseband modem, RF transceiver, power management, and system memory into one IC reduces the number of discrete components required, reduces bill-of-materials costs, and delivers a board-area savings of more than 50%. Handset OEMs can now offer smaller and sleeker designs at lower price points and benefit from reduced development time for quicker time to market.

Features of the QSC1100 include 65-nm process technology for enhanced performance and cost effectiveness; multiple frequency operation, including 450, 800, 1900, and 2100 MHz; a fourth-generation core voice codec suite (called Vocoder) that gives network operators the flexibility to prioritize voice quality or network capacity; linear interference cancellation; and support for color displays and a speakerphone.

The QSC1100 is expected to sample by the second half of 2007. For more information, visit www.cdmatech.com/singlechip.
