3V ±10% ■ Industrial temperature range:  –40°C to +85°C ■ Available in 32-pin (5mm x 5mm) QFN Package APPLICATIONS ■ All SONET and all GigE clock distribution ■ All Fibre Channel clock and data distribution ■ Network routing engine timing distribution ■ High-end, low-skew multiprocessor synchronous clock distribution DESCRIPTION Precision Edge® The SY58033U is a 2.
5V/3.
3V precision, high-speed, fully differential 400mV LVPECL 1:8 fanout buffer.
The SY58033U is optimized to provide eight identical output copies with less than 20ps of skew and only 76fsRMS phase jitter.
It can process clock signals as fast as 5.
5GHz.
The differential input includes Micrel’s unique, 3-pin input termination architecture that allows the SY58033U to directly interface to LVPECL, CML, and LVDS differential signal (AC‑ or DC-coupled) without any level-shifting or termination resistor networks in the signal path.
The result is a clean, stub-free, low-jitter solution.
The LVPECL (100k temperature compensated) outputs feature a 400mV typical swing into 50 ohms loads, and provide an extremely fast rise/fall time guaranteed to be less than 80ps.
The SY58033U operates from a 2.
5V ±5% supply or 3.
3V ±10% supply and is guaranteed over the full industrial temperature range (–40°C to +85°C).
Other high-speed 1:8 fanout buffers include the CML SY58031...
