CY22381FC Clock Generator Equivalent & Substitute Parts

Part Overview

The CY22381FC is a Clock Generator and Fanout Distribution IC manufactured by Infineon Technologies, operating at a maximum frequency of 200MHz with a 1:3 input-to-output ratio. This device features an integrated Phase-Locked Loop (PLL) with bypass capability, accepting LVTTL and Crystal inputs while providing CMOS outputs. The CY22381FC is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CY22381FC is determined by strict equivalence across the following critical parameters:

• Frequency - Max: 200MHz
• Input Type: LVTTL, Crystal
• Output Type: CMOS
• Number of Circuits: 1
• Ratio - Input:Output: 1:3
• PLL Configuration: Yes with Bypass
• Voltage - Supply: 3.135V ~ 3.465V
• Operating Temperature: 0°C ~ 70°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The CY22381FXC meets all parametric requirements for direct substitution. The primary distinction between these parts is product status and compliance certification, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CY22381FXC is the direct parametric equivalent to the CY22381FC. Selection between these parts should be based on the following factors:

Product Status: The CY22381FC is obsolete, while the CY22381FXC is active. For new designs or long-term production requirements, the CY22381FXC is the appropriate choice.

Compliance Certification: The CY22381FXC is ROHS3 compliant, whereas the CY22381FC is RoHS non-compliant. Applications subject to RoHS regulations require the CY22381FXC.

Electrical and Functional Equivalence: Both parts are electrically and functionally identical across all specified parameters, including frequency, input/output types, supply voltage, operating temperature range, and package configuration.

Packaging: The CY22381FXC is supplied in tube packaging, while the CY22381FC packaging specification is not provided. Both use the same 8-SOIC physical package.

Frequently Asked Questions (FAQ)

Q: Can the CY22381FXC directly replace the CY22381FC in existing designs?

A: Yes. The CY22381FXC is parametrically equivalent to the CY22381FC across all electrical and functional specifications. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The CY22381FC is classified as obsolete, indicating that Infineon Technologies no longer manufactures or supports this part. The CY22381FXC is active and continues to be manufactured, ensuring availability for procurement and technical support.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance is a regulatory and environmental certification, not a functional parameter. The CY22381FXC's ROHS3 compliance makes it suitable for applications subject to RoHS regulations. Both parts are electrically identical.

Q: Are the 8-SOIC packages identical between these parts?

A: Yes. Both the CY22381FC and CY22381FXC use the 8-SOIC (0.154", 3.90mm Width) package. PCB footprints and mounting procedures are identical.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts have an MSL rating of 3 (168 Hours), indicating identical moisture handling and storage requirements.

Q: Are there any electrical parameter differences between these parts?

A: No. The supply voltage range (3.135V ~ 3.465V), operating temperature range (0°C ~ 70°C), maximum frequency (200MHz), input/output types, and all other electrical specifications are identical.
