SY89221U Overview
The SY89221U is a 2.5/3.3V precision, high-speed, integrated clock divider and LVPECL fanout buffer capable of handling clocks up to 1.5GHz. Optimized for munications applications, the four independently controlled output banks are phasematched and can be configured for pass through ÷1, ÷2 or ÷4 divider ratios. The differential input includes Micrel’s unique, 3-pin input termination architecture that allows the user...
