Microchip | SY89840UMG

The SY89840UMG is a Part of SY89840U Series, low jitter PECL, 2:1 differential input multiplexer (MUX) optimized for redundant source switchover applications.
 
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 LVPECL output
• Guaranteed AC performance over temperature and supply voltage:
• Wide operating frequency: 1 kHz to >1.5 GHz
• < 880ps In-to-Out tpd
• < 190ps 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)
• 800 mV LVPECL output swing
• 2.5 V ±5% or 3.3 V ±10% supply voltage

Applications:

• Redundant clock distribution
• Fail-safe clock protection
