ICS9248162

The ICS9248162 is the single chip clock solution for various mobile chipset platforms. It provides all necessary clock signals for such a system. Spread spectrum may be enabled through IZC programming. Spread spectrum typically reduces system EMI by 8dB to 10dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9248-162 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.

The features of ICS9248162 can be summarized as (1)up to 137MHz frequency support ; (2)spread spectrum for EMI control ; (3)serial i2c interface for power management, frequency select, spread spectrum; (4)provides the following system clocks -4-CPUs @ 2.5/3.3\L up to l37MHz. (including CPUCLK_F)- 9-SDRAMs up to 137MHZ(including SDRAM_F)- 8-PCI @3 .3\L CPU/2 or CPU/3(including 1 free rtmning PCICLK_F) -1-24/48MHz @3.3V -1-43MHz @3.3V Hxed-2-REF 14.3 3MHz. ; (5)efficient power management scheme through PCI and CLK STOP CLOCKS ; (6)spread spectrum & 0 to down spread.

The absolute maximum ratings of ICS9248162 are (1)supply voltage: 5 .5V; (2)logic inputs: GND -0.5 to Vpp +0.5V; (3)ambient operating temperature: 0°C to +70°C; (4)case temperature: 115°C; (5)storage temperature: -65°C to +150°C(stresses above those listed underxlbsolute 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.)
