Application Scenarios & Design Considerations

Low Power, 3GHz, 1:2 LVPECL Fanout Buffer/Translator with Internal Termination

Alternative Part Number

  • NB6L11MMNG --: Differential fanout buffer in the same 3.3V LVPECL class with similar low-skew performance, available in a comparable small package.
  • MC100EP11DTG --: ECL/PECL 1:2 differential fanout buffer offering similar signaling and skew characteristics, widely used as a drop-in style replacement.
  • ICS853S011BGILF --: Low-skew 1:2 differential-to-LVPECL fanout buffer with comparable supply and output levels, suitable for clock distribution applications.
  • ICS854S006AGILF --: Low-skew clock fanout buffer with comparable output count and supply range, suitable as a functional drop-in for clock distribution designs.
  • CDCLVC1106PWR --: Six-output LVCMOS clock buffer with low additive jitter, usable as an alternative fanout solution when differential signaling is not mandatory.
