Application Scenarios & Design Considerations

Precision LVPECL Runt Pulse Eliminator 2:1 Multiplexer

Alternative Part Number

  • NB7L86MMNG --: Differential clock/data receiver with similar low-voltage differential signaling function and comparable package, suitable as a functional replacement.
  • MAX9374EKA+T --: High-speed differential line receiver/translator offering similar signal conditioning performance for clock distribution applications.
  • SN65LVDS100DGK --: LVDS repeater/translator that can serve as an alternative for differential signal buffering in similar high-speed designs.
  • NB6L11MMNG --: Pin-compatible 1:2 differential fanout buffer in the same 16-pin QFN package with similar LVDS/LVPECL signaling and supply range, widely available from a different vendor.
  • MC100EP11DTG --: ECL/PECL 1:2 differential fanout buffer offering comparable high-speed performance and output drive, usable as a functional substitute with minor supply/termination adjustments.
  • ADCLK944BCPZ --: High-speed clock fanout buffer with similar differential output capability and low jitter, suitable as an alternative when layout and supply rails are adapted.
