... HIGH-PERFORMANCE PHASE LOCKED LOOP DESCRIPTION The SY89421V is a digital Phase Locked Loop based on Micrel-Synergy's differential PLL technology 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 locking and tracking characteristics ...
