Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS9FG108DGILFT is determined by strict equivalence across the following critical parameters:

• Frequency output specification (400MHz maximum)
• Input-to-output frequency ratio (1:9)
• Output signal type (HCSL)
• Supply voltage range (3.135V ~ 3.465V)
• Operating temperature range (-40°C ~ 85°C)
• Physical package (48-TFSOP)
• Application domain (Intel CPU Server, PCIe, SATA)
• PLL functionality requirement

The substitute part 9FG108EGILFT meets all these criteria and is manufactured by the same supplier, ensuring functional and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 9FG108EGILFT is a direct functional equivalent to the ICS9FG108DGILFT. The primary distinction is product status: the original part is Obsolete, while the substitute is Active. The substitute part carries RoHS3 Compliance certification, providing enhanced environmental and regulatory alignment for new designs and long-term supply chain stability.

Both parts share identical electrical specifications, package geometry, and application scope. The substitute is available in Tape & Reel (TR) packaging, which is standard for production environments. Selection of the 9FG108EGILFT eliminates obsolescence risk while maintaining full electrical and mechanical compatibility.
