LMK04100 (ACTIVE) Precision Clock Conditioners Clock Jitter Cleaner with Cascaded PLLs

 

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.
