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 LLP package and are footprint compatible with other clocking devices in the same family.
