Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADCLK944BCPZ is an ultra-fast clock fan-out buffer, manufactured using ADI's proprietary XFCB3 silicon-germanium (SiGe) bipolar process. This device is designed for high-speed applications that require low jitter performance.

This device features one differential input with a center tap, differential, and 100 Ω on-chip termination resistor. It supports DC-coupled LVPECL, CML, 3.3V CMOS (single-ended) inputs, and AC-coupled 1.8V CMOS, LVDS, and LVPECL inputs. The VREF pin can be used to provide bias for AC-coupled inputs.

The ADCLK944BCPZ features four full-swing emitter-coupled logic (ECL) output drivers. For the LVPECL (positive ECL) output, VCC can be biased to the positive power supply and VEE to ground. For ECL output, VCC can be biased to ground and VEE to the negative power supply.

• 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.
