■ OVERVIEW
The SM5840 is a digital oversampling filter fabricated using NPCs proprietary Molybdenum gate CMOS technology. It is designed for use in digital audio playback systems, and supports 32.0, 44.1 and 48.0 kHz input sample rates and four- or eight-times oversampling. In addition to the oversampling filters, the SM5840 also incorporates digital de-emphasis, attenuation and soft mute functions for improved system performance and simpler design.
