Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The SI5351B-B02073-GMR is an I2C-configurable clock generator that is particularly well suited for replacing crystals, crystal oscillators, voltage-controlled crystal oscillators (VCXOs), phase-locked loops (PLLs), and fan-out buffers in cost-sensitive applications.

Based on a PLL/VCXO + high-resolution MultiSynth divider architecture, the SI5351B-B02073-GMR can generate arbitrary frequencies up to 200 MHz on each output with an error of 0 ppm.

The SI5351B-B02073-GMR incorporates an internal VCXO, enabling flexible replacement of free-running clocks and synchronised clocks. It eliminates the need for high-cost custom tunable crystals while providing reliable operation over a wide tuning range.

SI5351B-B02073-GMR Features and Specifications

I2C Programmable: User-defined configuration via the I2C interface allows flexible setting of frequency and output parameters.

High-Precision Frequency Synthesis: Precise frequency synthesis is achievable on each output with an error of 0 ppm.

Low Jitter: Output period jitter is less than 70 ps pp.typ, suitable for applications requiring high clock accuracy.

Multiple Input Options: Supports external crystal (XTAL), control voltage input (VC), or clock input (CLKIN), depending on the device version (A/B/C).

Spread Spectrum Functionality: Configurable spread spectrum functionality helps reduce electromagnetic interference (EMI).

Static phase offset support: Supports static phase offset, suitable for applications requiring precise clock alignment.

High-linearity VCXO: Integrated high-linearity VCXO eliminates the need for an external adjustable crystal, reducing system cost.

• 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.
