2.6-GHz delta-sigma fractional-N PLL with 800-MHz integer-N PLL

LMX2470SLEX General Description

One of the key advantages of the delta-sigma architecture is its ability to push fractional spurs and phase noise energy to higher frequencies, resulting in enhanced performance. With a programmable modulator up to order four, the LMX2470 provides flexibility for designers to fine-tune phase noise, spurious signals, and lock time requirements to meet specific system needs

Key Features

  • Low In-Band Phase Noise and Low Fractional Spurs
  • 12 Bit or 22 Bit Selectable Fractional Modulus
  • Up to 4th Order Programmable Delta-Sigma Modulator
  • Enhanced Anti-Cycle Slip Fastlock Circuitry
    • Fastlock
    • Cycle Slip Reduction
    • Integrated Timeout Counters
  • Digital Lock Detect Output
  • Prescalers Allow Wide Range of N Values
    • RF PLL: 16/17/20/21
    • IF PLL: 8/9 or 16/17
  • Crystal Reference Frequency up to 110 MHz
  • On-chip Crystal Reference Frequency Doubler.
  • Phase Comparison Frequency up to 30 MHz
  • Hardware and Software Power-down Control
  • Ultra Low Consumption: ICC = 4.1 mA (Typical)
