Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DIR9001PWR is a digital audio interface receiver that receives a 28 kHz to 108 kHz sampling frequency, 24-bit data word, dual-phase encoded signal.The DIR9001PWR complies with IEC60958-3, JEITA CPR-1205, AES3, and EBUtech3250 standards and can be used in a variety of applications that require a digital audio interface.

The DIR9001PWR supports a variety of output system clocks and output data formats for flexible use in a wide range of applications. Since all functions provided by the DIR9001PWR can be directly controlled via the control pins, it can easily be used in applications without a microcontroller. In addition, since dedicated pins are provided for the channel status bits and user data bits, their information can be easily processed by connecting a microcontroller, DSP, or other device.

Without the use of an internal actual sampling frequency calculator, the decoding operation of the DIR9001PWR does not require an external clock source or resonator. As a result, system costs can be reduced.

The DIR9001PWR's operating temperature range is specified from -40°C to 85°C, making it suitable for automotive applications.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
