DIGITAL AUDIO INTERFACE RECEIVER

FEATURES

DESCRIPTION

● STANDARD DIGITAL AUDIO INTERFACE

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.

RECEIVER (EIAJ1201)

● SAMPLING RATE: 32/44.1/48/96kHz

● RECOVERS 256/384/512f_SSYSTEM CLOCKS

● VERY LOW CLOCK JITTER:

100ps (with 20pF load)

● FLEXIBLE SYSTEM CLOCK OUTPUT

● SELECTABLE OUTPUT PCM AUDIO
