DESCRIPTION

· The TPA5050 is a stereo digital audio lip-sync delay device with I2C control, designed to synchronize audio streams with video streams in systems with complex video processing algorithms.

· It accepts a single serial audio input, buffers the data for a selectable period, and outputs the delayed audio data on a single serial output.

· The device supports delay times up to 170 ms per channel at a sampling frequency of 48 kHz, and multiple devices can be connected in series for additional delay.

FEATURES

· High Definition TV Lip-Sync Delay capability.

· Supports digital audio formats including 16-24-bit I2S, Right-Justified, and Left-Justified.

· I2C bus controlled with a single serial input port.

· Operates at 3.3 V with 5 V tolerant I/O and I2C control.

· Supports audio bit clock rates from 32 to 64 times the sampling frequency (fs = 32 kHz – 192 kHz).

· No external crystal or oscillator required; all internal clocks are generated from the audio clock.

· Available in a surface mount 4mm × 4mm, 16-pin QFN package.

APPLICATIONS

· Flat Panel TV Lip-Sync Delay.

· Home Theater Rear-Channel Effects.

· Wireless Speaker Front-Channel Synchronization.
