SY89837U
Description
The SY89837U is a low jitter, low skew, high-speed 1:8 fanout buffer with a unique, 2:1 differential input multiplexer (MUX) optimized for clock redundant switchover applications. Unlike standard multiplexers, the SY89837U unique 2:1 runt pulse eliminator (RPE) input MUX prevents any short cycles or “runt” pulses during switchover.
Key Features
- Selects between two clocks, and provides 8 precision, low skew LVPECL output copies
- Guaranteed AC performance over temperature and supply voltage
- Wide operating frequency: 1kHz to >1.5GHz
- <975ps in-to-out tpd
- <180ps tr/tf
- <40ps output-to-output skew
- Unique input isolation design minimizes crosstalk
- Ultra-low jitter design
- 150fs RMS phase jitter
- <0.7psrms MUX crosstalk induced jitter
