Note 1: Parameter is guaranteed by design and characterization. Not 100% tested in production. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These ratings are stress specifications only and functional operation of the device at these or any other conditions above those listed in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.

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.
