Overview
Integrated Circuit Systems, Inc.
ICS9134-06 ICS9134-07 Advance Information 32 kHz Motherboard Frequency Generator General Description The ICS9134-06 and ICS9134-07 are designed to generate clocks for all 286, 386, 486, Pentium and RISC-based motherboards, including laptops and notebook computers.
The only external components required are a 32.
768 kHz crystal and decoupling capacitors.
The device generates the 14.
318 MHz system clock, eliminating the need for a 14.
318 MHz crystal.
High performance applications may require high speed clock termination components.
The chip includes three independent clock generators plus the 32.
768 kHz reference clock to produce all necessary frequencies, including real time clock/DRAM refresh, master clock, CPU clock, keyboard clock, floppy disk controller clock, serial communications clock and bus clocks.
Different frequencies from clocks #2 can be selected using the frequency select pins, but clock #1 will be at 14.
318 MHz for all standard versions.
