ICS83940D - 1-TO-18 LVPECL-TO-LVCMOS / LVTTL FANOUT BUFFER

General Description

The ICS83940D is a low skew, 1-to-18 LVPECLto-LVCMOS/LVTTL Fanout Buffer and a member HiPerClockS™ of the HiPerClockS™ family of High Performance Clock Solutions from ICS.

The ICS83940D has two selectable clock inputs.

The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels.

Key Features

  • 18 LVCMOS/LVTTL outputs.
  • Selectable LVCMOS_CLK or LVPECL clock inputs.
  • PCLK, nPCLK supports the following input types: LVPECL, CML, SSTL.
  • LVCMOS_CLK accepts the following input levels: LVCMOS or LVTTL.
  • Maximum output frequency: 250MHz.
  • Output skew: 150ps (maximum).
  • Part to part skew: 750ps (maximum).
  • Additive phase jitter, RMS: < 0.03ps (typical).
  • Full 3.3V and 2.5V or mixed 3.3V core, 2.5V output supply modes.
