One device allows delay of up to 85 ms/ch (fs = 48 • 3.3 V Operation With 5 V Tolerant I/O and I2C kHz) to synchronize the audio stream to the video Control stream in systems with complex video processing • Supports Audio Bit Clock Rates of 32 to 64 fs algorithms. If more delay is needed, the devices can with fs = 32 kHz–192 kHz be connected in series. Independent clocks can be • No External Crystal or Oscillator Required used for each audio input. – All Internal Clocks Generated From the Audio Clock • Independent Clocks for Each Audio Input • Surface Mount 4mm × 4mm, 16-pin QFN Package Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
