IDT PC MAIN CLOCK
1520D—01/06/11
32-pin CK505 for Intel Systems
1
DATASHEET
Pin Configuration
Recommended Application:
Main clock for Intel 5/6 series desktop/embedded chipsets
Output Features:
1 - Low power push-pull CPU pair
1 - Low power push-pull SRC pair
1 - Low power push-pull 120MHz DISP/100MHz SRC pair
1 - Low power push-pull SATA/100MHz SRC pair
1 - Low power push-pull DOT96M pair
1 - 14.318M 3.3V REF output
Key Specifications:
CPU cycle to cycle jitter <85ps
SRC cycle to cycle jitter <85ps
PCIe Gen2 compliant
Features/Benefits:
CPU synchronous with SRC/CPU and SRC can be
interchanged for board routing
Default 0.5% down spread modulation/Reduces EMI
External 14.318M XTAL/allows precise frequency tuning
Fully integrated VREG for low power outputs/reduces
board space
Integrated 33ohm Rs on differential outputs/reduces
external component cost
SMBus Interface/unused outputs can be disabled
