Description: Notebook PC system Frequency Generator

Features

* Generates system clocks for CPU, IOAPIC, SDRAM, PCI, USB plus 14.318 MHz (REF0:1)
* MODE input pin selects optional power management input control pins (reconfigures pins 26 and 27)
* Two fixed outputs separately selectable as 24-MHz or 48-MHz (default = 48-MHz)
* V

Applications

* Output voltage swing is controlled by voltage applied to VDDQ3. REF0 is stronger than REF1 and should be used for driving ISA slots. Set to logic 1 for 3.3V CPU I/O. 95- or 100-MHz Input Selection: Selects power-up default CPU clock frequency as shown in Table 1 on page 1 (also determines SDRAM and
