APPLICATIONS

DESCRIPTION

The DIR1701 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

DIR1701 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.

The significant advantages of the DIR1701 are

96 kHz sampling rate capability and Low-jitter

clock recovery by the Sampling Period Adaptive

Controlled Tracking (SpAct

) system. Input signal

is reclocked with the patented Sampling period

Adaptive controlled tracking system for maximum

quality. These two 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 96 kHz sampling

rate.

This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate

precaustions. 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.

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.
