Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

8A34004E-000NBG8 is a Synchronization Management Unit for packet based and physical layer based equipment synchronization.

8A34004E-000NBG8 is a highly integrated device that provides tools to manage timing references, clock sources, and timing paths for IEEE 1588 and Synchronous Ethernet based clocks.

Feature

Two independent timing channels

4 Differential / 8 LVCMOS outputs

2 differential / 4 single-ended clock inputs

Reference monitors qualify/disqualify references depending on LOS, activity, frequency monitoring, and/or LOS input pins

Automatic reference selection state machines select the active reference for each DPLL based on the reference monitors, priority tables, revertive / non-revertive, and other programmable settings

System APLL operates from fundamental-mode crystal: 25MHz to 54MHz or from a crystal oscillator

System DPLL accepts an XO, TCXO, or OCXO operating at virtually any frequency from 1MHz to 150MHz

DPLLs can be configured as DCOs to synthesize Precision Time Protocol (PTP) / IEEE 1588 clocks

DPLL Phase detectors can be used as Time-to-Digital Converters (TDC) with precision below 1ps

Supports 1MHz I2C or 50MHz SPI serial processor ports

1 JTAG Boundary Scan

-40°C to +85°C operating temperature range

7mm x 7mm VFQFPN48 package

Applications

Core and access IP switches / routers

Synchronous Ethernet equipment

Telecom Boundary Clocks (T-BCs) and Telecom Time SlaveClocks (T-TSCs) according to ITU-T G.8273.2

10Gb, 40Gb, and 100Gb Ethernet interfaces

Central Office Timing Source and Distribution

Wireless infrastructure for 4.5G and 5G network equipment 

• 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.
