Texas Instruments has introduced 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. This 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.
The 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.

The industry-leading jitter performance of the DIR9001 makes it an ideal data and clock source for TI's high-performance digital-to-analog converter (DAC) products, such as the PCM1792A, to provide the highest performance DAC output available today. The DIR9001 also complements TI's wide range of S/PDIF and sample rate conversion (SRC) technologies for consumer and professional audio applications. TI's digital audio interface products range from 96-kHz receivers and transmitters to
combination 216-kHz SRC and S/PDIF transceivers capable of 144 db SRC.

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.
