The 8531-01 is a low skew, high performance 1-to-9 Differential-to-3.3V LVPECL Fanout Buffer and a member of the family of High Performance Clock Solutions from IDT. The 8531-01 has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. Guaranteed output skew and part-to-part skew characteristics make the 8531-01 ideal for high performance workstation and server applications.

Features

  • Nine differential 3.3V LVPECL outputs
  • Selectable differential CLK, nCLK or LVPECL clock inputs
  • CLK, nCLK pair can accept the following differential input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
