1.3 DESCRIPTION
The LMK04816 family is the industry's highest performance clock conditioner with superior clock jitter
cleaning, generation, and distribution with advanced features to meet next generation system
requirements. The dual loop PLLatinum™ architecture enables 111 fs rms jitter (12 kHz to 20 MHz) using
a low noise VCXO module or sub-200 fs rms jitter (12 kHz to 20 MHz) using a low cost external crystal
and varactor diode.
