SY89421V 5V/3.3V HIGH-PERFORMANCE PHASE LOCKED LOOP

The SY89421V is a digital Phase Locked Loop based on Micrel-Synergy's differential PLL technology. It is capable of operating in the 30MHz to 560MHz reference input frequency range, and up to 2000MHz with the HFIN input and an external VCO. Use of a phase-frequency detector results in excellent PLL .
