Clock Generator IC OVERVIEW The SM8702AM is a clock generator IC that can generate clock signals up to and exceeding 100MHz for personal computer (PC) motherboards.

It uses a single 14.318MHz crystal oscillator element and 2 built-in PLLs to simultaneously and independently generate 2 CPU clocks, 6 PCI bus clocks, 2 reference clocks with the same frequency as the crystal element, 48MHz USB interface clock, and 24MHz Super I/O chip clock outputs.
