LMK04000 Family Low-Noise Clock Jitter Cleaner with Cascaded PLLs .. July 24, 2009 LMK04000 Family Low-Noise Clock Jitter Cleaner with Cascaded PLLs 1.0 General Description 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 bined with an external crystal and varactor diode, the LMK04000 family provides sub-200 femtosecond (fs) root mean square (RMS) jitter performance. The cascaded architecture consists of two high-performance phase-locked loops (PLL), a...
