NB3N510xx Series Clock Generators

The NB3N510x series from ON Semiconductor is a family of precision, low-phase noise clock generators that supports PCI Express and sRIO clock requirements. These devices accept a 25 MHz fundamental mode parallel resonant crystal or a 25 MHz single-ended reference clock signal and generate differential HCSL/LVDS outputs. Clock outputs can be individually enabled/disabled through hardware input pins. In addition, these devices provide selectable spread options for applications demanding low-electromagnetic interference (EMI) as well as optimum performance with no spread option.

NB3N510xx Family of Devices Features

    NB3N51032: Clock generator, 3.3 V, crystal to 25 MHz, 100 MHz, 125 MHz, and 200 MHz dual HCSL/LVDS
  • Precision, low-phase noise clock generator that supports PCI express and Ethernet requirements
  • Accepts a 25 MHz fundamental-mode parallel resonant crystal and generates a differential HCSL output at 25 MHz, 100 MHz, 125 MHz, or 200 MHz clock frequencies
  • Outputs can interface with LVDS with proper termination
  • Selectable spread options of 0.5% and - 0.75% for applications demanding low-electromagnetic interference (EMI) - no spread setting is also available.
    NB3N51034: Quad HCSL/LVDS clock generator, 3.3 V, crystal to 100 MHz/200 MHz
  • Takes a 25 MHz fundamental-mode parallel resonant crystal and generates four differential HCSL/LVDS outputs at 100 MHz or 200 MHz
  • Provides selectable spread options of 0.5%, −1.0%, −1.5%, for applications demanding low-electromagnetic interference (EMI) - no spread setting is also available.
