Product Description

The PI6C48535-11B is a high-performance low jitter and low-skew LVPECL fanout buffer. PI6C48535-11B features selectable of single-ended clock or crystal inputs and translates to four LVPECL outputs. The CLK input accepts LVCMOS or LVTTL signals. The outputs are synchronized with input clock during asynchronous assertion/deassertion of CLK_EN pin. PI6C48535-11B is ideal for crystal or LVCMOS/LVTTL to LVPECL translation. Typical clock translation and distribution applications are data-communications and telecommunications.


  • Maximum output frequency: 500MHz
  • 4 pair of differential LVPECL outputs
  • Selectable CLK and crystal inputs
  • CLK accepts LVCMOS, LVTTL input level
  • Ultra low additive phase jitter: < 0.05 ps (typ) (differential 156.25MHz, 12KHz to 20MHz integration range)
  • Output Skew: 30ps (maximum)
  • Part-to-part skew: 200ps (maximum)
  • Propagation delay: 1.5ns (maximum)
  • 3.3V power supply
  • Pin-to-pin compatible to ICS8535-11, ICS8535-31
  • Operating Temperature: -40°C to 85°C
  • Packaging (Pb-free & Green available):
    - 20-pin TSSOP (L)
