The PI6C49S1504T is a high-performance fanout buffer device which supports up to 1.5GHz frequency. This device is ideal for systems that need to distribute low-jitter clock signals to multiple destinations.


  • 4 differential outputs with 2 banks
  • User-configurable output signaling standard for each bank:
  • LVCMOS reference output up to 200MHz
  • Up to 1.5GHz output frequency for differential outputs
  • Ultra-low additive phase jitter: < 0.03ps (typ) (differential
    156.25MHz, 12KHz to 20MHz integration range)
  • Selectable reference inputs support either single-ended
    or differential or Xtal
  • Low skew between outputs within banks (<40ps)
  • Low delay from input to output (Tpd typ. < 1.5ns)
  • Separate input output supply voltage for level shifting
  • 2.5V / 3.3V power supply
  • Industrial temperature support
  • Totally Lead-Free & Fully RoHS Compliant 
  • Halogen and Antimony Free. “Green” Device 
  • For automotive applications requiring specific change control
    (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and
    manufactured in IATF 16949 certified facilities), please contact
    us or your local Diodes representative.
  • Packaging (Pb-free & Green):
    • 32-pin, TQFN (ZH)
