Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX2871ETJ is an ultra-wideband phase-locked loop (PLL), integrated voltage-controlled oscillator (VCO) that operates in both integer and fractional n-division modes. When used in combination with external reference oscillators and loop filters, the MAX2871 is a high-performance frequency synthesizer capable of synthesizing frequencies from 23.5MHz to 6.0GHz while maintaining excellent phase noise and spurious performance.

With multiple integrated Vcos covering the 3000MHz to 6000MHz range, and with output dividers from 1 to 128, the ultra-wide frequency range is possible. The device also offers dual differential output drivers that can be programmed independently to provide output power from -1dBm to +8dBm. Both outputs can be silenced by software or hardware control.

Features:

The output binary buffer/divider supports extended frequency range

The frequency division ratio is 1/2/4/8/16/32/64/128

23.5MHz to 6000MHz

High performance frequency phase discriminator (PFD) and reference frequency reduce spectrum noise

PFD up to 140MHz

Reference frequency up to 210MHz

Normalized in-band phase noise as low as -230 DBC /Hz reduces the system's background noise contribution

Manual or automatic VCO selection allows for fast switching

Output phase reset and adjustment allows multiple frequency synthesizers to synchronize

An on-chip temperature sensor with a 7-bit ADC ensures a reasonable choice of VCO

Cycle reduction and quick lock feature increase accuracy and speed up sampling

Maintaining a VCO lock over the entire temperature range enables burr free operation

The dual differential programmable output fully improves the flexibility of use

Applications:

Clock generation

Microwave radio

Test and measurement

Wireless infrastructure

• 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.
