CY2308SI-3 Equivalent & Substitute Parts

Part Overview

The CY2308SI-3 is a Fanout Buffer (Distribution) Zero Delay Buffer IC manufactured by Infineon Technologies, designed for clock distribution applications requiring 133.3MHz maximum frequency operation. This device features a 1:8 input-to-output ratio with integrated Phase-Locked Loop (PLL) functionality in a 16-SOIC surface mount package.

The CY2308SI-3 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CY2308SI-3 are determined by equivalence across the following critical parameters:

• Frequency maximum rating (133.3MHz)
• Input-to-output ratio (1:8)
• Input and output signal compatibility (LVCMOS, LVTTL input; LVCMOS output)
• PLL functionality (present)
• Supply voltage range (3V ~ 3.6V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (16-SOIC)
• Divider/Multiplier capability (Yes)

The identified substitute parts maintain identical electrical and mechanical specifications while differing in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the CY2308SI-3, the CY2308SXI-4 is the primary substitute due to its Active product status, ensuring long-term availability and continued manufacturing support. This part maintains full electrical and mechanical compatibility while providing ROHS3 compliance.

The CY2308SXI-3 serves as a secondary substitute option. Although electrically equivalent, its Last Time Buy status indicates limited future availability and should be selected only when CY2308SXI-4 procurement is constrained.

Both substitute parts provide improved compliance posture compared to the original CY2308SI-3, which carries RoHS non-compliant status.

Frequently Asked Questions (FAQ)

Q: Are CY2308SXI-4 and CY2308SXI-3 direct pin-for-pin replacements for CY2308SI-3?

A: Yes. All three parts share identical package type (16-SOIC), pinout configuration, and electrical specifications. No PCB layout modifications are required for substitution.

Q: What is the difference between CY2308SXI-4 and CY2308SXI-3?

A: Both parts are electrically and mechanically identical. The primary difference is product lifecycle status: CY2308SXI-4 is Active, while CY2308SXI-3 is Last Time Buy. For new designs and ongoing production, CY2308SXI-4 is preferred.

Q: Can I use CY2308SI-3 and CY2308SXI-4 interchangeably in the same circuit?

A: Yes. The parts are functionally equivalent across all specified electrical parameters including frequency rating, signal levels, supply voltage, and operating temperature range.

Q: What does RoHS3 compliance mean for these parts?

A: ROHS3 compliance indicates the parts meet Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. The CY2308SI-3 is RoHS non-compliant, while CY2308SXI-4 and CY2308SXI-3 are ROHS3 compliant.

Q: Does packaging differ between these parts?

A: CY2308SI-3 packaging is unspecified in available data. CY2308SXI-4 and CY2308SXI-3 are supplied in Tube packaging. Both maintain the same 16-SOIC case format suitable for surface mount assembly.

Q: What is the Moisture Sensitivity Level (MSL) requirement for storage?

A: All three parts carry MSL 3 rating, requiring storage conditions not exceeding 168 hours at 85°C and 85% relative humidity before soldering.
