General 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 I
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.
