Overview

SM5921A 8-channel Lip Sync Delay OVERVIEW The SM5921A is an SDRAM controller LSI for audio applications.

It stores 64-fs slot 3-wire serial format audio data input at sampling frequency fs in SDRAM, and can access data at an arbitrary address to add a delay to each channel data.

It also has a direct mute function to mute the audio data.
