LMX2485E Datasheet High Performance Delta-sigma Low Power Dual Pllatinum Frequency Synthesizers

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. LMX2485/LMX2485E High Performance Delta-Sigma Low Power Dual PLLatinum Frequency Synthesizer February 2006 LMX2485/LMX2485E 50 MHz - 3.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LMX2485 is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL.

The device 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 n RF PLL: 8/9/12/13 or 16/17/20/21 n IF PLL: 8/9 or 16/17 Advanced Delta Sigma Fractional Compensation n 12 bit or 22 bit selectable fractional modulus n Up to 4th order programmable delta-sigma modulator Features for Improved Lock Times and Programming n Fastlock / Cycle slip reduction n Integrated time-out counter n Single word write to change frequencies with Fastlock Wide Operating Range n LMX2485 RF PLL: 500 MHz to 3.0 GHz n LMX2485E RF P.
