Product Description

The PI6C48545 is a high-performance low-skew LVDS fanout buffer. PI6C48545 features two selectable single-ended clock inputs and translate to four LVDS 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. PI6C48545 is ideal for single-ended LVTTL/LVCMOS to LVDS translations. Typical clock translation and distribution applications are data-communications and telecommunications.


  • Maximum operation frequency: 650 MHz
  • 4 pair of differential LVDS outputs
  • Selectable CLK0 and CLK1 inputs
  • CLK0, CLK1 accept LVCMOS, LVTTL input level
  • Output Skew: 40ps (maximum)
  • Part-to-part skew: 300ps (maximum)
  • Propagation delay: 2.2ns (maximum)
  • 3.3V power supply
  • Pin-to-pin compatible to ICS8545
  • Operating Temperature: -40°C to 85°C
  • Packaging (Pb-free & Green): - 20-pin TSSOP (L)
