DESCRIPTION
The LMK03002/LMK03002C 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 four LVPECL clock output
distribution blocks.
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 LVPECL output buffer. This allows multiple
integer-related and phase-adjusted copies of the
reference to be distributed to four system
components.
The clock conditioners come in a 48-pin WQFN
package and are footprint compatible with other
clocking devices in the same family.
