SY89841U Description
The SY89841U is a low jitter LVDS, 2:1 input multiplexer (MUX) optimized for redundant source switchover applications. Unlike standard multiplexers, the SY89841U unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover. In addition, a unique Fail-safe Input protection prevents metastable conditions when the selected input clock fails to a DC voltage (voltage between the...
SY89841U Key Features
- Selects between two sources, and provides a glitch-free, stable LVDS output
- Guaranteed AC performance over temperature and supply voltage
- wide operating frequency: 1kHz to >1.5GHz
- <870ps In-to-Out tpd
- <150ps tr/tf The differential input includes Micrel’s unique, 3-pin
- Unique patent-pending input isolation design input termination architecture that allows customers minimizes crosstalk to
- Ultra-low jitter design: signal path. The outputs are 350mV, LVDS with fast
- <1psrms random jitter rise/fall times guaranteed to be less than 150ps
- <1psrms cycle-to-cycle jitter
- <10pspp total jitter (clock) The SY89841U operates from a 2.5V ±5% supply
