DESCRIPTION
The DIR1703 is a digital audio interface receiver (DIR) which receives and decodes audio data up to 96 kHz according to the AES/EBU, IEC958, S/PDIF, and EIAJCP340/1201 consumer and professional format interface standards. The DIR1703 demultiplexes the channel status bit and user bit directly to serial output pins, and has dedicated output pins for the most important channel status bits. It also includes extensive errors reporting. The significant advantages of the DIR1703 are 96-kHz sampling rate capability and Low-jitter clock recovery by the Sampling Period Adaptive Controlled Tracking (SpAct) system. The input signal is reclocked with the patented Sampling period Adaptive controlled tracking system for maximum quality. These features are required for recent consumer and professional audio instruments, in which the DIR has an interface to any kind of delta-sigma type ADC/DAC with a 96-kHz sampling rate.

This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

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. SpAct and Burr-Brown are trademarks of Texas Instruments.
PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
