Product Description

The PI6C48535-01 is a high-performance low-skew LVPECL fanout buffer. PI6C48535-01 features two selectable single-ended clock inputs and translates to four LVPECL outputs. The CLK0 and CLK1 inputs accept LVCMOS or LVTTL signals. The outputs are synchronized with input clock during asynchronous assertion/ deassertion of CLK_EN pin. PI6C48535-01 is ideal for singleended LVTTL/LVCMOS to LVPECL translations. Typical clock translation and distribution applications are data-communications and telecommunications.


  • Maximum operation frequency: 500 MHz
  • 4 pair of differential LVPECL outputs
  • Selectable CLK0 and CLK1 inputs
  • CLK0, CLK1 accept LVCMOS, LVTTL input level
  • Output Skew: 80ps (maximum)
  • Part-to-part skew: 150ps (maximum)
  • Propagation delay: 1.9ns (maximum)
  • 3.3V power supply
  • Additive jitter of 36.7fs (typical)
  • Operating Temperature: -40°C to 85°C
  • Packaging (Pb-free & Green available):
  • 20-pin TSSOP (L)
