LMK04131 - Clock Jitter Cleaner with Cascaded PLLs

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.
