IDT PC MAIN CLOCK
1520A—03/16/10
32-pin CK505 for Intel Systems
1
DATASHEET
Pin Configuration
Recommended Application:
CK505 clock, 32-pin for 5 series Intel chipsets
Output Features:
1 - CPU differential low power push-pull pairs
1 - SRC differential low power push-pull pairs
1 - Selectable 120MHz or 100MHz CK_SSC_Disp low power
push-pull pair
1 - SATA/SRC selectable differential low power push-pull pair
1 - DOT differential low power push-pull pair
1 - REF, 14.318MHz
Key Specifications:
CPU outputs cycle-cycle jitter < 85ps
SRC output cycle-cycle jitter < 125ps
+/- 100ppm frequency accuracy on all outputs
SRC are PCIe Gen2 compliant
Features/Benefits:
Supports spread spectrum modulation, default is 0.5%
down spread
Uses external 14.318MHz crystal, external crystal load
caps are required for frequency tuning
Does not require external pass transistor for voltage
regulator
Integrated 33 series resistors on differential outputs,
Zo=50
Not recommended for new designs. The last time buy
date for this product is 5/19/2011.
Please refer to PDN K-10-18.
