The LMK03000 family of precision clock conditioners combine the functions of jitter
cleaning/reconditioning, multiplication, and distribution of a reference clock. The devices
integrate a Voltage Controlled Oscillator (VCO), a high performance Integer-N Phase Locked Loop
(PLL), a partially integrated loop filter, and up to eight outputs in various LVDS and LVPECL
The VCO output is optionally accessible on the Fout port. Internally, the VCO output
goes through a VCO Divider to feed the various clock 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
The clock conditioners come in a 48-pin WQFN package and are footprint compatible with
other clocking devices in the same family.
