Features & Applications

The SY89843UMG is a low jitter PECL, 2:1 differential input multiplexer (MUX) optimized for redundant source switchover applications.

The SY89843U unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover. In addition, a unique Fail-Safe Input protection prvents metastable conditions when the selected input clock fails to a DC voltage

Features:

  • Selects between two sources, and provides a glitch-free,stable LVPECL output
  • Guaranteed AC performance over temperature and supply voltage:
  • – Wide operating frequency: 1k Hz to >1.5 GHz
  • – < 880 ps In-to-Out tpd
  • – < 190 ps tr/tf
  • Unique patent-pending input isolation design minimizes crosstalk
  • Fail-Safe Input prevents oscillations
  • Ultra-low jitter design:
  • – <1psRMS random jitter
  • – <1psRMS cycle-to-cycle jitter
  • – <10psPP total jitter (clock)
  • – <0.7psRMS MUX crosstalk induced jitter
  • 800 mV LVPECL output swing
  • 2.5 V ±5% or 3.3 V ±10% supply voltage
  • –40°C to +85°C industrial temperature range
  • Available in 24-pin (4mm x 4mm) MLF Package

Applications:

  • Redundant clock switchover
  • Failsafe clock protection
