General Description
Features
ICS9159-07
Frequency Generator for NexGen Nx586 Systems
ICS9159-07RevC060697P
Block Diagram
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.
Either synchronous (2XCPU/3) or asynchronous (32 MHz)
PCI bus operation can be selected. Green PC systems are
supported through doze mode.
Three CPU clocks operate up to 65 MHz at 3.3V, plus
smooth transitions
Selection of nine frequencies, tristate
Seven BUS clocks support sync or async bus
operation
Integrated buffer outputs drive up to 10pF loads
3.13 to 5.25V (3.3±5%, 5.0±5%) supply range
28-pin SOIC package
Clock duty cycles 45/55
NexGen is a trademark of NexGen Corporation.
Applications
Ideal for NexGen Nx586 PCI-based motherboard designs
