Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD9854ASVZ digital frequency synthesizer is a highly integrated suite that uses advanced DDS technology, plus two internal high-speed, high-performance orthogonal Dacs, to form digitally programmable I and Q frequency synthesizer capabilities. The AD9854 generates highly stable frequency, phase, and amplitude-programmable sine and cosine outputs for use as agile LO in communications, radar, and many other applications when benchwritten against a precise clock source. The AD9854's innovative high-speed DDS core offers 48-bit frequency resolution (1 μHz tuning resolution when using 300 MHz SYSCLK). Maintaining 16-bit resolution for phase-to-amplitude conversion ensures excellent spury-free dynamic range (SFDR).

The circuit architecture of the AD9854ASVZ allows the generation of synchronous orthogonal output signals at frequencies up to 150 MHz, and the ability to digitally tune these output signals at new frequencies up to 100 million times per second. For agile clock generator applications, the (externally filtered) sine wave output can be converted to a square wave by an internal comparator. This kit provides two 14-bit phase registers and a single pin for BPSK operations.

• 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.
