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.
