FOUR CHANNEL DIGITAL AUDIO LIP-SYNC DELAY WITH I²C CONTROL

FEATURES

•

APPLICATIONS

Digital Audio Format: 16-24-bit I²S,

Right-Justified, Left-Justified

•

High Definition Lip-Sync Delay

Flat Panel TV Lip-Sync Delay

Home Theater Rear Channel Effects

Wireless Speaker Front-Channel

Synchronization

•

I²C Bus Controlled

Dual Serial Input Ports

Delay Time: 85 ms/ch at fs = 48 kHz

Delay Resolution: One Sample

DESCRIPTION

Delay Memory Cleared on Power-Up or After

Delay Changes

The TPA5051 accepts two serial audio inputs,

buffers the data for a selectable period of time, and

outputs the delayed audio data on two serial outputs.

One device allows delay of up to 85 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. Independent clocks can be

used for each audio input.

– Eliminates Erroneous Data on Output

•

3.3 V Operation With 5 V Tolerant I/O and I²C

Control

Supports Audio Bit Clock Rates of 32 to 64 fs

with fs = 32 kHz–192 kHz

No External Crystal or Oscillator Required

– All Internal Clocks Generated From the

Audio Clock

•

Independent Clocks for Each Audio Input
