SY89465U Overview
Key Specifications
Mount Type: Surface Mount
Pins: 44
Operating Voltage: 2.5 V
Max Voltage (typical range): 2.625 V
Description
The SY89465U is a low-jitter, 1:10 LVDS fanout buffer with a 2:1 differential input multiplexer (MUX) optimized for redundant source switchover applications. Unlike standard multiplexers, the SY89465Us 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover.
Key Features
- Selects between two sources, and provides 10 precision LVDS copies
- Unique, patent-pending input isolation design minimizes adjacent channel crosstalk
- Fail-Safe Input prevents oscillations
- Ultra-low jitter design: – 183 fsRMS phase jitter (typical) – <0.7psRMS MUX crosstalk-induced jitter
- Unique patented input termination and VT pin accepts DC- and AC-coupled inputs (CML, PECL, LVDS)
- 325mV LVDS output swing
- 2.5V ±5% supply voltage
- 40°C to +85°C industrial temperature range
