LMK02000 - Precision Clock Distributor with Integrated PLL

The LMK02000 precision clock conditioner combines the functions of jittercleaning/reconditioning, multiplication, and distribution of a reference clock. The deviceintegrates a high performance Integer-N Phase Locked Loop (PLL), three LVDS, and five LVPECL clockoutput distribution blocks.

Each clock distribution block includes a programmable divider, a phase synchronizationcircuit, a programmable delay, a clock output mux, and an LVDS or LVPECL output buffer. This allowsmultiple integer-related and phase-adjusted copies of the reference to be distributed to eightsystem components.

The clock conditioner comes in a 48-pin WQFN package and is footprint compatible withother clocking devices in the same family.
