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.
