• Package / Case: 48-TFSOP (0.240", 6.10mm Width)
• Frequency - Max: 400MHz
• Voltage - Supply: 3.135V ~ 3.465V
• Operating Temperature: -40°C ~ 85°C
• Output Type: HCSL
• Input Type: Clock, Crystal
• Number of Circuits: 1
• Ratio - Input:Output: 1:9
• Differential - Input:Output: No/Yes
• PLL: Yes
• Main Purpose: Intel CPU Server, PCI Express (PCIe), SATA

The substitute part 9FG108EGILF meets all electrical and mechanical specifications required for direct replacement. The primary distinction is product status: the substitute is Active, whereas the main part is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 9FG108EGILF is a direct functional equivalent to the ICS9FG108DGILF. Both parts share identical electrical specifications, package geometry, and application requirements for Intel CPU Server, PCI Express (PCIe), and SATA clock generation.

Frequently Asked Questions (FAQ)

Q: Can the 9FG108EGILF directly replace the ICS9FG108DGILF in existing designs?

A: Yes. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical specifications, package dimensions (48-TFSOP), frequency output (400MHz), supply voltage range (3.135V ~ 3.465V), and operating temperature range (-40°C ~ 85°C). Pin-to-pin compatibility is maintained.

Q: What is the primary difference between these two parts?

A: The main difference is product status. The ICS9FG108DGILF is Obsolete, while the 9FG108EGILF is Active. The substitute also carries ROHS3 compliance certification. All functional and electrical parameters remain identical.

Q: Are there packaging differences between the main part and substitute?

A: No. Both parts use the 48-TFSOP package (0.240", 6.10mm Width) with Surface Mount mounting type. The substitute is available in Tube packaging, whereas the main part packaging is not specified.

Q: What applications are these parts suitable for?

A: Both parts are designed for Intel CPU Server, PCI Express (PCIe), and SATA clock generation applications. They function as frequency synthesizers with 1:9 input-to-output ratio and spread spectrum capability.

Q: Are there any compliance or regulatory considerations when substituting?

A: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99). The substitute carries additional ROHS3 compliance, which is beneficial for environmental regulatory requirements. Moisture sensitivity levels are equivalent (MSL 1 - Unlimited).
