3 Description

The DIR9001 is a digital audio interface receiver that

can receive a 28-kHz to 108-kHz samplingfrequency,

24-bit-data-word, biphase-encoded signal.

The DIR9001 complies with IEC60958-3, JEITA CPRIEC60958

1205 (Revised version of EIAJ CP-1201), AES3,

EBUtech3250, and it can be used in various

applications that require a digital audio interface.

The DIR9001 supports many output system clock and

output data formats and can be used flexibly in many

application systems. As the all functions which the

DIR9001 provides can be controlled directly through

control pins, it can be used easily in an application

system that does not have a microcontroller. Also, as dedicated pins are provided for the channel-status bit

and user-data bit, processing of their information can

be easily accomplished by connecting with a

microcontroller, DSP, or others.

The DIR9001 does not require an external clock

source or resonator for decode operation if the

internal actual-sampling-frequency calculator is not

used. Therefore, it is possible to reduce the cost of a

system.

The operating temperature range of the DIR9001 is

specified as –40°C to 85°C, which makes it suitable for automotive applications.
