DESCRIPTION
The LMK04100 family of precision clock conditioners
provides jitter cleaning, clock multiplication and
distribution without the need for high-performance
VCXO modules.
When connected to a recovered system reference
clock and a VCXO, the device generates 5 low jitter
clocks in LVCMOS, LVDS, or LVPECL formats.
