LMK03000 Family
Precision Clock Conditioner with Integrated VCO
General Description
The LMK03000 family of precision clock conditioners com-
bine the functions of jitter cleaning/reconditioning, multiplica-
tion, and distribution of a reference clock. The devices
integrate a Voltage Controlled Oscillator (VCO), a high per-
formance Integer-N Phase Locked Loop (PLL), a partially
integrated loop filter, and up to eight outputs in various LVDS
and LVPECL combinations.
The VCO output is optionally accessible on the Fout port. In-
ternally, the VCO output goes through a VCO Divider to feed
the various clock distribution blocks.
Each clock distribution block includes a programmable di-
vider, 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 com-
ponents.
The clock conditioners come in a 48-pin LLP package and are
footprint compatible with other clocking devices in the same
family.
