SY89464U
Overview
The SY89464U is a low jitter 1:10 LVPECL fanout buffer with a 2:1 differential input multiplexer (MUX) optimized for redundant source switchover applications. Unlike standard multiplexers, the SY89464U’s unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover.
- Selects between two sources, and provides 10 precision LVPECL copies
- Guaranteed AC performance over temperature and supply voltage: - Wide operating frequency: 1kHz to >1.5GHz - < 1100ps In-to-Out tpd - < 220ps tr/tf
- Unique, patent-pending MUX input isolation design minimizes adjacent channel 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
