ICS9248-80
Description
The ICS9248-80 is a general purpose system clock. It provides 8 output CLKs, 1 REF CLK and excellent power management features through CLK_STOP#. Spread spectrum may be enabled through I2C programming. Spread spectrum typically reduces EMI by 8d B to 10 d B. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9248-80 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.
