Microchip | SY89841UMG

The SY89841UMG is a Part of SY89841U Series, low jitter PECL, 2:1 input multiplexer (MUX) optimized for redundant source switchover applications. Unlike standard multiplexers, this unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover.

It comes in a Package of MLF-16 and its operating temperature ranges from -40 °C to 85 °C.

Features:

• Selects between two sources, and provides a glitch-free, stable LVDS output
• Guaranteed AC performance over temperature and supply voltage:
• wide operating frequency: 1 kHz to >1.5 GHz
• <870ps In-to-Out tpd
• <150ps 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
• Unique patent-pending input termination and VT pin accepts DC-coupled and AC-coupled inputs
  (CML, PECL, LVDS)
• 350 mV LVDS output swing

Applications:

• Redundant clock switchover
• Fail-safe clock protection
