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. www.DataSheet4U.
