General Description
ICS9169C-41 General Description
The ICS9169C-41 is a Clock Synthesize/Driver chip for Pentium, PentiumPro or Cyrix 68x86 based motherboards using SDRAM.
Features include four dual purpose I/O pins which provide extra CPU clocks and enable the part to be packaged in a low-cost 34-pin SSOP package. These four pins latch the select inputs at the internal Power-On Reset. Additionally, the device meets the Pentium and PentiumPro power-up stabilization, which requires that CPU and PCI clocks be stable within 2ms after power-up.
The ICS9169C-41 clock outputs are designed for low EMI emissions. Controlled rise and fall times, unique output driver circuits and innovative circuit layout techniques enable the ICS9169C-41 to have lower EMI than other clock devices.
The ICS9169C-41 accepts a 14.318MHz reference crystal or clock as its input and runs from a 3.3V supply.
