DESCRIPTION
D
Standard Digital Audio Interface Receiver
(EIAJ1201)
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.

On-Chip Master Clock Oscillator, Only an
External Crystal Is Required:
24.576 / 22.5792 / 18.432 / 16.9344 / 16.384 /
12.288 / 11.2896 / 8.192 / 6.144 / 5.6448 /
4.096 MHz Crystals Are Available
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.
