Description

The DIR9001 is a digital audio interface receiver that can receive a 28-kHz to 108-kHz sampling- frequency, 24-bit-data-word, biphase-encoded signal. The DIR9001 complies with IEC60958-3, JEITA CPR-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, etc.

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.
