49% FPO 170 0 ® DIR1700 DIR PRELIMINARY INFORMATION SUBJECT TO CHANGE WITHOUT NOTICE 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 OPERATION MODES ● SELECTABLE ERROR FLAG FUNCTION ● OUTPUTS CHANNEL STATUS DATA FLAG WITH BLOCK START SIGNAL VDD DGND ● OUTPUTS USER BIT DATA Parity ● SINGLE +5V POWER SUPPLY ERF ERSNS D0 Error Check D1 DAT Data Format Select BCK LRCK ● 28-LEAD SSOP PACKAGE SCLK DIN Clock and Data Recover Mute CS1 Data Output Timing CS2 CS3 CS24 PLL lock or unlock FIL PLL CS25 Clocks VLFLG 258/384/512fs VCO STOP Oscillation Select CSBIT UDAT BLSTRT AGND VCC Xtal Oscillation STOP 256/384/512 Select Xtal Oscillation Clock Xtal Bias Network CLKSEL Xtal Existence Auto-Detection OSCSEL XTO XTI International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
