STEREO DIGITAL AUDIO LIP-SYNC DELAY WITH I²C CONTROL

FEATURES

•

APPLICATIONS

Digital Audio Formats: 16-24-bit I²S,

Right-Justified, Left-Justified

•

High Definition TV Lip-Sync Delay

Flat Panel TV Lip-Sync Delay

Home Theater Rear-Channel Effects

Wireless Speaker Front-Channel

Synchronization

•

I²C Bus Controlled

Single Serial Input Port

Delay Time: 170 ms/ch at fs = 48 kHz

Delay Resolution: One Sample

DESCRIPTION

Delay Memory Cleared on Power-Up or After

Delay Changes

The TPA5050 accepts a single serial audio input,

buffers the data for a selectable period of time, and

outputs the delayed audio data on a single serial

output. One device allows delay of up to 170 ms/ch

(fs = 48 kHz) to synchronize the audio stream to the

video stream in systems with complex video

processing algorithms. If more delay is needed, the

devices can be connected in series.
