SY89851U
Overview
The SY89851U is a low jitter, low skew, high-speed 1:2 differential fanout buffer optimized for precision telecom and enterprise server distribution applications. The SY89851U distributes clock frequencies from DC to >3GHz, and data rates to 2.5Gbps guaranteed over temperature and voltage.
- Precision 1:2, 800mV LVPECL fanout buffer
- Low power consumption: 80mW typ. (2.5V)
- Guaranteed AC performance over temperature and voltage: - DC to >3GHz clock throughput - <340ps propagation delay - <180ps rise/fall time - <20ps output-to-output skew
- Ultra-low jitter design: - <1psRMS random jitter - <10psPP deterministic jitter - <10psPP total jitter (clock)
- Unique, patented input termination and VT pin accepts DC- and AC-coupled inputs (CML, LVPECL, LVDS)
- 100K LVPECL-compatible outputs
- Power supply 2.5V ±5% or 3.3V ±10%
- -40°C to +85°C industrial temperature range
- Available in 16-pin (3mm x 3mm) MLF™ package Functional Block Diagram
