9FG830AFILF Equivalent & Substitute Parts

Part Overview

The 9FG830AFILF is a Clock/Frequency Generator IC manufactured by Renesas Electronics Corporation, designed for Intel QPI and PCI Express (PCIe) applications. This 48-SSOP surface mount device generates a 400MHz output from clock or crystal input, featuring HCSL and LVTTL output formats with a 1:9 input-to-output ratio and integrated PLL functionality.

The 9FG830AFILF is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this frequency generator.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 9FG830AFILF is evaluated based on the following critical parameters that define functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Supply voltage range: 3.135V ~ 3.465V (must match or encompass)
• Operating temperature range: -40°C ~ 85°C (must match or exceed)
• Input type: Clock or Crystal input capability
• Output format: HCSL and/or LVCMOS compatibility
• PLL functionality: Required for frequency multiplication
• Number of circuits: Single circuit configuration

Mechanical Compatibility Criteria:

• Surface mount packaging
• Pin count and footprint compatibility
• Moisture sensitivity level: MSL 3 or better

Regulatory Compliance:

• RoHS3 compliance
• REACH unaffected status

The 9FGL0841CKILF qualifies as a substitute based on matching supply voltage, operating temperature range, input/output capabilities, PLL presence, and regulatory compliance. Differences in maximum frequency (100MHz vs. 400MHz), output ratio (1:8 vs. 1:9), and package form factor (48-VFQFN vs. 48-BSSOP) must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 9FG830AFILF and 9FGL0841CKILF are obsolete products manufactured by Renesas Electronics Corporation and maintain identical supply voltage specifications (3.135V ~ 3.465V) and operating temperature ranges (-40°C ~ 85°C). Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary technical differences are maximum frequency capability (400MHz vs. 100MHz), input-to-output ratio (1:9 vs. 1:8), and package form factor (48-BSSOP vs. 48-VFQFN). Selection between these parts depends on whether the application requires the higher frequency output of the 9FG830AFILF or can operate within the 100MHz maximum of the 9FGL0841CKILF. Package footprint differences necessitate PCB layout modifications if substitution is implemented.

Both parts feature PLL functionality, accept clock or crystal inputs, and provide HCSL output compatibility. The 9FG830AFILF provides LVTTL output, while the 9FGL0841CKILF provides LVCMOS output; output format compatibility with downstream circuitry must be confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 9FGL0841CKILF directly replace the 9FG830AFILF without PCB modifications?

A: No. The 9FGL0841CKILF uses a 48-VFQFN package (6x6mm) while the 9FG830AFILF uses a 48-BSSOP package. Different footprints require PCB layout changes. Pin-to-pin compatibility is not guaranteed and must be verified against device datasheets.

Q: What is the primary limitation of using the 9FGL0841CKILF as a substitute?

A: The maximum output frequency is 100MHz compared to 400MHz for the 9FG830AFILF. Applications requiring 400MHz output cannot use this substitute. The input-to-output ratio differs (1:8 vs. 1:9), affecting frequency multiplication calculations.

Q: Are the supply voltage and operating temperature ranges identical?

A: Yes. Both devices operate at 3.135V ~ 3.465V supply voltage and -40°C ~ 85°C operating temperature range, ensuring thermal and power supply compatibility.

Q: Do both parts support the same input types?

A: Yes. Both the 9FG830AFILF and 9FGL0841CKILF accept clock or crystal inputs, providing flexibility in clock source selection.

Q: What is the difference in output format between these parts?

A: The 9FG830AFILF provides HCSL and LVTTL outputs. The 9FGL0841CKILF provides HCSL and LVCMOS outputs. Both share HCSL compatibility. Downstream circuitry must support either LVTTL or LVCMOS input levels accordingly.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 9FG830AFILF and 9FGL0841CKILF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these products are no longer in active production by Renesas Electronics Corporation. Availability is limited to existing inventory. Long-term design continuity may require evaluation of current-generation clock generator alternatives.
