Broadcom introduced a more energy efficient digital-to-analog (DTA) system-on-a-chip (SoC) for cable set-top box (STB) OEMs. The new Broadcom DTA chip, which uses 65 nanometer technology, is based upon the earlier generation BCM3543 SoC that is used in many terrestrial broadcast designs and is ENERGY STAR-compliant.http://www.broadcom.com
