In-system programmable from 1 MHz and 340 MHz via I2C/SPI

Digital frequency pulling (DCO) via I2C/SPI

  • Output frequency pulling with perfect pull linearity

  • 13 programmable pull range options to ±3200 ppm

  • Frequency pull resolution as low as 5 ppt (0.005 ppb)

Dynamic performance

  • 0.1 ppb/g, superior shock and vibration resistance

  • No activity dips or micro jumps

Integrated LDO for on-chip power supply noise filtering

  • 0.05 ps/mV power supply noise rejection (PSNR)

  • Reduces BOM by eliminating a LDO

Programmable LVPECL, LVDS, or HCSL output

  • Programmable LVPECL, LVDS Swing

  • LVDS Common Mode Voltage Control

  • Optimizes signal integrity

Superior reliability

  • 1 billion hours MTBF

  • Lifetime Warranty: Reduces repair costs and field failures due to clock components

  • 10G to 100G Ethernet
  • Data Centers
  • Test & Measurement
