LMK03000/LMK03000C/LMK03001/LMK03001C
Precision Clock Conditioner with Integrated VCO
General Description
The LMK03000/LMK03000C/LMK03001/LMK03001C preci-
sion clock conditioners combine the functions of jitter clean-
ing/reconditioning, multiplication, and distribution of a refer-
ence clock. The devices integrate a Voltage Controlled
Oscillator (VCO), a high performance Integer-N Phase
Locked Loop (PLL), a partially integrated loop filter, three
LVDS, and five LVPECL clock output distribution blocks.
The VCO output is optionally accessible on the Fout port. In-
ternally, the VCO output goes through an Input 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.
