CS42L73

Low Power Mobile Stereo CODEC

概要

製品概要

CS42L73 is a highly integrated, low-power, mobile audio distribution network that incorporates two stereo DACs and a stereo ADC with ground centered headphone, line and speaker amplifiers for smartphone and portable applications. Three asynchronous bidirectional serial ports with integrated asynchronous sample rate converters (ASRCs) that accept a wide range of incoming audio sample rates can be used to feed the integrated digital mixing engine, which is the heart of the CS42L73. The engine can simultaneously overlay and distribute digital audio from up to three external sources to any of its integrated audio nodes, giving complete routeability to the mobile system designer.
