Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The 8T49N287A-040NLGI is a FemtoClock® NG eight-channel frequency converter with two fractional feedback PLLS, which can be used as a jitter attenuator and frequency converter. With a six-integer and two-decimal output divider, this frequency converter can generate up to eight different output frequencies (8kHz to 1GHz). Eight different outputs can be selected among LVPECL, LVCMOS, LVDS or HCSL output levels. The following are the key features:

Supports SDH/SONET and synchronous Ethernet clocks, including all FEC rate conversions

Jitter: <0.3ps RMS (typical value, including spurious, 12kHz to 20MHz)

Lock to input signal, hold and freely run working modes

The initial hold accuracy is +50ppb

Up to two LVPECL, LVDS, LVHSTL, HCSL or LVCMOS input clocks are accepted:

The accepted frequency range is from 8kHz to 875MHz

Automatic and manual input clock selection, uninterrupted switching

Clock input monitoring, including support for intermittent clock speeds

The phase slope limit and the completely uninterrupted switching option can control the output clock phase transients

It operates with a basic mode crystal ranging from 10MHz to 40MHz

Generate 8 LVPECL/LVDS/HCSL or 16 LVCMOS output clocks:

The output frequency range is from 8kHz to 1.0GHz (differential)

The output frequency range is from 8kHz to 250MHz (LVCMOS)

Four general-purpose I/O (GPIO) pins with optional status and control support:

Four output enable control inputs can be mapped to any one of the eight outputs

Lock, hold and signal loss status output

Open leak interrupt pin

Nine programmable loop bandwidth Settings for each PLL: 1.4Hz to 360Hz

Optional quick lock function

Programmable output phase delay, with a step size as small as 16ps

Registers can be programmed via I2C or an external I2C EEPROM

Bypass clock path for system testing

Ambient operating temperature: -40°C to 85°C

56QFN lead-free (RoHS 6) package

The 8T49N287A-040NLGI frequency converter supports uninterrupted reference switching between input clocks. These frequency converters can monitor the signal loss (LOS) of all input clocks and issue an alarm when an input clock failure is detected. Typical applications include 1G, 10G, 40G and 100G synchronous Ethernet, SONET/SDH, baseband of wireless base stations, data communication and OTN decommapping.

• 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.
