LMX2487E Datasheet High Performance Delta-sigma Low Power Dual Pllatinum Frequency Synthesizers

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LMX2487E High Performance Delta-Sigma Low Power Dual PLLatinum Frequency Synthesizer May 2007 LMX2487E 7.5 GHz High Performance Delta-Sigma Low Power Dual PLLatinum™ Frequency Synthesizers with 3.

General Description

The LMX2487E is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL.

It is fabricated using National Semiconductor’s advanced process.

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

Key Features

  • Quadruple Modulus Prescalers for Lower Divide Ratios.
  • 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 Features for Improved Lock Times and Programming.
  • Fastlock / Cycle slip reduction.
  • Integrated time-out counter.
  • Single word write to change frequencies with Fastlock Wide Operating Range.
  • LMX2487E RF PLL:.
