The ICS9159-07 is a low-cost frequency generator designed specifically for NexGen Nx586 systems. The integrated buffer minimizes skew and provides the CPU clocks required by the NexGen Nx586 microprocessor. A 14.318 MHz XTAL oscil-lator provides the reference clock to generate standard Nx586 frequencies. The CPU clock makes gradual frequency transi-tions without violating the PLL timing of internal microproc-essor clock multipliers.
