DIR9001-Q1中文资料汽车类 24 位 96kHz 数字音频接口接收器数据手册TI规格书

描述 Description

The DIR9001-Q1 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-Q1 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-Q1 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-Q1 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-Q1 does not require an external clock source or resonator for decode operation if theinternal 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-Q1 is specified as -40°C to 85°C, which makes it suitable for automotive applications.
