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.


Description

The ICS9250-28 is part of a two chip clock solution for 810/810E and 815 type chipset. Combined with the ICS9112-17, the ICS9250-28 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 iterations or costly shielding. The ICS9250-28 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.
