ICS9248-78 General Description

The ICS9248-78 is a single chip clock for Intel Pentium II. It provides all necessary clock signals for such a system. Spread spectrum may be enabled through I2C programming. Spread spectrum typically reduces EMI by 8dB to 10 dB. This simplifies EMI qualification without resorting to board design it.
