Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The 8A34005-000NLG IEEE 1588 System Synchronizer generates ultra-low jitter precise timing signals based on the IEEE 1588 Precise Time Protocol (PTP) and Synchronous Ethernet (SyncE). PLL channels can act independently as a frequency synthesizer, jitter attenuator, numerical control oscillator (DCO), or digital phase-locked loop (DPLL).

Features

Four independent timing channels

Jitter output below 150fs RMS (typical)

Digital PLLs (DPLLs) lock to any frequency from 0.5Hz to 1GHz

DPLLs / Digitally Controlled Oscillators (DCOs) generate any frequency from 0.5Hz to 1GHz

DCO outputs can be aligned in phase and frequency with the outputs of any DPLL or DCO

DPLLs comply with ITU-T G.8262 for Synchronous Ethernet (SyncE)

IEEE 1588 Support:

DCOs can be controlled by external IEEE 1588 software to synthesize Precision Time Protocol (PTP) / IEEE 1588 clocks with frequency resolution less than 1.11x10-16

Combo Bus simplifies compliance with ITU-T G.8273.2

Precise (1ps) resolution for phase measurement and control

All outputs/inputs can be configured to decode/encode PWM clock signals

PWM can be used to transmit and receive embedded frame and sync pulses; as well as Time of Day (ToD) and other data

Device requires a crystal oscillator or fundamental-mode crystal: 25MHz to 54MHz

Optional XO_DPLL input allows a wider range for XO, TCXO or OCXO frequencies from 1MHz to 150MHz for applications that require a local oscillator with high stability

Serial processor ports support 1MHz I2C or 50MHz SPI

• 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.
