The PI6C49X0208 is a high performance multi-voltage 8-outputs CMOS Fanout Buffer with internal Crystal Oscillator. The XTAL range is from 10MHz to 50MHz. The device has a wide range of operating voltages of 2.5V and 3.3V. The device also provides user selectable output VDD option, which provides excellent flexibility to users. This device is ideal for systems that need to distribute low jitter clock signals to multiple destinations.


  • 8 single-ended outputs fanout buffer
  • Up to 200MHz output frequency
  • Ultra low output additive jitter = 0.01ps (typical)
  • Selectable reference inputs support Xtal (10~50MHz), singleended and differential
  • Low output skew ~ 50ps (typical)
  • 5V/3.3V operation
  • User configurable output VDDO in different banks:
    • Mixed 3.3V core, 2.5V, 1.8V or 1.5V output operating supply
    • Mixed 2.5V core, 1.8V, 1.5V or 1.2V output operating supply
  • Industrial temperature range: –40°C to +85°C
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony Free. “Green” Device (Note 3)
  • For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/104/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/
