Microchip Technology SY58021UMG-TR

Description
The SY58021U is a highspeed, precision 1:4 LVPECL fanout buffer with internal termination. It operates from a 2.5V ±5% or 3.3V ±10% supply and is guaranteed over the full industrial temperature range (40°C to 85°C). The SY58021U can process clock signals as fast as 4 GHz with low jitter performance (70 fSRMS phase jitter typical). It features a unique input termination architecture that interfaces to differential LVPECL, CML, and LVDS signals (AC or DCcoupled) as small as 100 mV without any levelshifting or termination resistor networks in the signal path. The outputs are 100K LVPECL compatible, with extremely fast rise/fall times guaranteed to 70 ps.
