NOTICE - The following device(s) are recommended alternatives:

The 8545-02 is a low skew, high performance 1-to-4 LVCMOS/LVTTL-to-LVDS Clock Fanout Buffer and a member of the  family of High Performance Clock Solutions from IDT. Utilizing Low Voltage Differential Signaling (LVDS) the 8545-02 provides a low power, low noise, solution for distributing clock signals over controlled impedances of 100Ω. The 8545-02 accepts an LVCMOS/LVTTL input level and translates it to 3.3V LVDS output levels. Guaranteed output and part-to-part skew characteristics make the 8545-02 ideal for those applications demanding well defined performance and repeatability.


  • Four differential LVDS output pairs
  • Two LVCMOS/LVTTL clock inputs to support redundant or selectable frequency fanout applications
  • Maximum output frequency: 350MHz
  • Translates LVCMOS/LVTTL input signals to LVDS levels
  • Output skew: 60ps (maximum)
  • Part-to-part skew: 450ps (maximum)
  • Propagation delay: 1.45ns (maximum)
  • Additive phase jitter, RMS: 0.14ps (typical)
  • Full 3.3Vsupply mode
  • 0°C to 70°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
