3 Description

The LMK02000 precision clock conditioner combines

the functions of jitter cleaning/reconditioning,

multiplication, and distribution of a reference clock.

The device integrates a high performance Integer-N

Phase Locked Loop (PLL), three LVDS, and five

LVPECL clock output distribution blocks.

Each clock distribution block includes a

programmable divider, a phase synchronization

circuit, a programmable delay, a clock output mux,

and an LVDS or LVPECL output buffer. This allows

multiple integer-related and phase-adjusted copies of

the reference to be distributed to eight system

components.

The clock conditioner comes in a 48-pin WQFN

package and is footprint compatible with other

clocking devices in the same family.
