TI DIR9001 Digital Audio Interface Receiver

Texas Instruments (NYSE: TXN) DIR9001 is a 24-bit, 96-kHz digital audio interface receiver that provides the industry’s best jitter performance as low as 50 ps RMS, which is four times better than the nearest stand-alone receiver. The highly-integrated device reduces the number of external components required and enhances sound quality in applications such as AV/DVD receivers and amplifiers, automotive audio systems, digital televisions, musical instruments, recording systems and high-performance PC audio interfaces.

Texas Instruments DIR9001 24-bit, 96-kHz Digital Audio Interface ReceiverThe DIR9001 allows the designer to control all functionality through the device’s hardware control pins, eliminating the need for an external microcontroller. Additionally, the DIR9001 integrates a high-performance phase-lock loop (PLL) to not only improve jitter performance but also remove the need for an external clock source when the sample frequency calculator is not used. Both features reduce the overall system cost by eliminating additional system components that competing digital audio interface receivers typically require.

DIR9001 Benefits:

  • Support for any input frequency from 28-kHz up to 108-kHz for stereo digital interfaces including S/PDIF, EIAJ CP-1201, IEC60958 and AES/EBU
  • Superior overall system noise performance provided by the flexible master clock outputs with as low as 50 ps jitter
  • Easier integration into existing designs with 5V-tolerant logic as well as selectable pulse-code-modulation (PCM) output formats
  • Higher system intelligence and integration with the main control processor via the separate user data, channel data and sampling frequency outputs
  • Wide ambient temperature range of -40C to +85C for automotive applications

The DIR9001 is available now in a 28-pin TSSOP lead-free package and is priced at $1.95 each in 1,000-piece quantities. Samples are available to ship within 24 hours of request.
