DESCRIPTION
DIR9001-Q1SLLS843A–JUNE 2007–REVISED FEBRUARY 2008
96-kHz, 24-Bit Digital Audio Interface Receiver Car Audio Head Units
23• One-Chip Digital Audio Interface Receiver
(DIR) Including Low-Jitter Clock-Recovery •
Car Audio External Amplifiers
System Compliant With Digital Audio Interface
Standards: IEC60958 (former IEC958), JEITA The DIR9001-Q1isa digital audio interface receiver
CPR-1205 (former EIAJ CP-1201, CP-340), that can receivea 28-kHz to 108-kHz sampling-
AES3, EBU tech3250 frequency, 24-bit-data-word, biphase-encoded signal.
The DIR9001-Q1 complies with IEC60958-3, JEITA•
Clock Recovery and Data Decode From CPR-1205 (Revised versionof EIAJ CP-1201), AES3,
Biphase Input Signal, Generally Called S/PDIF, EBUtech3250, andit can be used in various
EIAJ CP-1201, IEC60958, AES/EBU applications that requirea digital audio interface.•
Biphase Input Signal Sampling Frequency (fS) The DIR9001-Q1 supports many output system clock
Range: 28 kHzto 108 kHz and output data formats and can be used flexiblyin•
Low-Jitter Recovered System Clock:50ps many application systems. As theall functions which•
Jitter Tolerance Compliant With IEC60958-3 the DIR9001-Q1 provides can be controlled directly
through control pins,it can be used easilyin an•
Selectable Recovered System Clock: 128fS, application system that does not have a
256fS, 384fS, 512fS microcontroller. Also, as dedicated pins are provided•
Serial Audio Data Output Formats: 24-BitI2S; for the channel-status bit and user-data bit,
MSB-First, 24-Bit Left-Justified; MSB-First 16-, processing of their information can be easily
24-Bit Right-Justified accomplished by connecting witha microcontroller,
DSP, etc.•
User Data, Channel-Status Data Outputs
Synchronized With Decoded Serial Audio Data The DIR9001-Q1 does not require an external clock
No External Clock Required for Decode source or resonator for decode operationif the
internal actual-sampling-frequency calculatoris not•
Includes Actual Sampling Frequency used. Therefore,itis possibleto reduce the costofa
Calculator (Needs External 24.576-MHz Clock) system.•
Function Control: Parallel (Hardware)The operating temperature rangeof the DIR9001-Q1•
Functions Similar and Pin Assignments is specified as –40°C to 85°C, which makesit
Equivalentto Thoseof DIR1703 suitable for automotive applications.•
Single Power Supply: 3.3V (2.7Vto 3.6V) Wide Operating Temperature Range: –40°Cto
85°C 5 V-Tolerant Digital Inputs Package: 28-pin TSSOP, Pin Pitch: 0,65 mmPleasebe aware thatan important notice concerning availability, standard warranty, and usein critical applicationsof
Texas Instruments semiconductor products and disclaimers thereto appearsatthe endofthis data sheet.
