National Semiconductor LMK02000
The LMK02000 precision clock conditioner combines the functions of jitter cleaning/reconditioning, multiplication, and distribution of a reference clock. The device integrates a high performance Integer-N Phase Locked Loop (PLL), three LVDS, and five LVPECL clock output 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.| Part No. | LMK02000 |
