The LMK04000 family of precision clock conditioners provides low-noise jitter cleaning, clock multiplication and distribution without the need for high-performance voltage controlled crystal oscillators (VCXO) module. Using a cascaded PLLatinum™ architecture combined with an external crystal and varactor diode, the LMK04000 family provides sub-200 femtosecon.
