LMX2487 Datasheet Frequency Synthesizers

Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community LMX2487 SNAS322C – FEBRUARY 2006 – REVISED JANUARY 2016 LMX2487 1-GHz to 6-GHz High Performance Delta-Sigma Low-Power Dual PLLatinum™.

General Description

The LMX2487 device is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL.

It is fabricated using TI’s advanced process.

With delta-sigma architecture, fractional spurs at lower offset frequencies are pushed to higher frequencies outside the loop bandwidth.

Key Features

  • 1 Quadruple Modulus Prescaler for Lower Divides.
  • RF PLL: 16/17/20/21 or 32/33/36/37.
  • IF PLL: 8/9 or 16/17.
  • Advanced Delta Sigma Fractional Compensation.
  • 12-Bit or 22-Bit Selectable Fractional Modulus.
  • Up to 4th Order Programmable Delta-Sigma Modulator.
  • Improved Lock Times.
  • Fastlock / Cycle Slip Reduction With SingleWord Write to Change Frequencies.
  • Integrated Time-Out Counter.
  • Wide Operating Range.
