DESCRIPTION
DIR1700 is a Digital Audio Interface Receiver (DIR)
which is designed for consumer and professional digi-
tal audio applications, such as digital AV receivers.
DIR1700 has two system clock operation modes:
internal PLL operation mode and XTAL clock opera-
tion mode for systems which contain both digital and
analog inputs. The advantages of the DIR1700 are
very low clock jitter, and 96kHz sampling rate capa-
bility. These features are now required for consumer
and professional audio systems.
