National Semiconductor LMK03000C
The LMK03000/LMK03000C/LMK03001/LMK03001C 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, three LVDS, and five LVPECL clock output distribution blocks. The VCO output is optionally accessible on the Fout port.| Part No. | LMK03000C |

GENERAL DESCRIPTION
Internally, the VCO output goes through an Input 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 system components. The clock conditioners come in a 48-pin LLP package and are footprint compatible with other clocking devices in the same family.FEATURES
