DIGITAL AUDIO INTERFACE RECEIVER
FEATURES
DESCRIPTION
● STANDARD DIGITAL AUDIO INTERFACE
RECEIVER (EIAJ1201)
DIR1700 is a Digital Audio Interface Receiver (DIR)
which is designed for consumer and professional digital audio applications, such as digital AV receivers.
DIR1700 has two system clock operation modes:
internal PLL operation mode and XTAL clock operation mode for systems which contain both digital and
analog inputs. The advantages of the DIR1700 are
very low clock jitter, and 96kHz sampling rate capability. These features are now required for consumer
and professional audio systems.
● SAMPLING RATE: 32 /44.1/48/96kHz
● RECOVERS 256/384/512fS SYSTEM CLOCKS
● VERY LOW CLOCK JITTER:
100ps (with 20pF load)
● FLEXIBLE SYSTEM CLOCK OUTPUT
● SELECTABLE OUTPUT PCM AUDIO
DATA FORMAT
● XTAL CLOCK/PLL CLOCK
