CPR-1205 (former EIAJ CP-1201, CP-340),
High-End Audio/Sound Card for PC
AES3, EBU tech3250
Replacement of DIR1703
Clock Recovery and Data Decode From
Other Applications Requiring S/PDIF Receiver
Biphase Input Signal, Generally Called S/PDIF,
EIAJ CP-1201, IEC60958, AES/EBU
Biphase Input Signal Sampling Frequency (f
S)
The DIR9001 is a digital audio interface receiver that
Range: 28 kHz to 108 kHz
can
receive
a
28-kHz
to
108-kHz
sampling-
Low-Jitter Recovered System Clock: 50 ps
frequency, 24-bit-data-word, biphase-encoded signal.
The DIR9001 complies with IEC60958-3, JEITA
Jitter Tolerance Compliant With IEC60958-3
CPR-1205 (Revised version of EIAJ CP-1201),
Selectable Recovered System Clock: 128 f
S,
AES3, EBUtech3250, and it can be used in various
256 fS, 384 fS, 512 fS
applications that require a digital audio interface.
Serial Audio Data Output Formats: 24-Bit I2S;
The DIR9001 supports many output system clock
MSB-First, 24-Bit Left-Justified; MSB-First 16-,
and output data formats and can be used flexibly in
24-Bit Right-Justified
many application systems. As the all functions which
User Data, Channel-Status Data Outputs
the DIR9001 provides can be controlled directly
Synchronized With Decoded Serial Audio Data
through control pins, it can be used easily in an
application
system
that
does
not

Function Control: Parallel (Hardware)
accomplished by connecting with a microcontroller,
DSP, etc.
Functions Similar and Pin Assignments
Equivalent to Those of DIR1703
The DIR9001 does not require an external clock
source or resonator for decode operation if the
Single Power Supply: 3.3 V (2.7 V to 3.6 V)
internal actual-sampling-frequency calculator is not
Wide Operating Temperature Range: –40°C to
used. Therefore, it is possible to reduce the cost of a
85
°C
system.
5 V-Tolerant Digital Inputs
The operating temperature range of the DIR9001 is
Package: 28-pin TSSOP, Pin Pitch: 0,65 mm
specified as –40
°C to 85°C, which makes it suitable
for automotive applications.
