LMX2486 - Frequency Synthesizers

General Description

The LMX2486 device is a low-power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL.

The device is fabricated using TI’s advanced process.

Key Features

  • Quadruple Modulus Prescaler for Lower Divids.
  • 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 and Programming.
  • Fastlock / Cycle Slip Reduction Which Requires Only a Single-Word Write.
  • Integrated Time-Out Counter.
  • Wide Operating Range.
