Microchip | SY89838UMG

The SY89838UMG is a 2.5 V low jitter low skew high-speed 1:8 fanout buffer with a unique 2:1 differential input multiplexer (MUX) optimized for redundant source switch over applications

The differential input includes unique, 3-pin input termination architecture that allows customers to interface to any differential signal The SY89838U operates from a 2.5 V ±5% supply and is guaranteed over the full industrial temperature range of –40°C to +85°C

Features:

• Selects between two clocks, and provides 8 precision, low skew LVDS output copies
• 2:1 MUX input provides a glitch-free, stable LVDS output
• Guaranteed AC performance over temperature and supply voltage:
• Wide operating frequency: 1 kHz to >1.5 GHz
  • <150ps tr/tf
  • <40ps output-to-output skew
• Unique patent-pending input isolation design minimizes crosstalk
• Fail-safe input prevents oscillation
• Ultra-low jitter design:
  • <1psRMS random jitter
  • <1psRMS cycle-to-cycle jitter
  • <10psPP total jitter (clock)
  • <0.7psRMS MUX crosstalk induced jitter
• 350 mV LVDS output swing
• Power supply 2.5 V +5%
• –40°C to +85°C industrial temperature range

Applications:

• Redundant clock switchover
• Failsafe clock protection
