Equivalent & Substitute Parts for 23S08-2DCG8

Part Overview

The Renesas Electronics 23S08-2DCG8 is a Clock Multiplier with Zero Delay Buffer IC designed for 133.3MHz operation in a 16-SOIC surface mount package. This component provides 1:8 input-to-output ratio multiplication with integrated PLL and bypass capability, supporting LVTTL input and CMOS/LVTTL output configurations.

The 23S08-2DCG8 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this legacy device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 23S08-2DCG8 are identified based on the following critical parameters that determine functional compatibility:

Mandatory Compatibility Parameters:

• Package / Case: 16-SOIC (0.154", 3.90mm Width) — ensures PCB footprint compatibility
• Mounting Type: Surface Mount — maintains assembly process compatibility
• Voltage - Supply: 3V ~ 3.6V — ensures power supply compatibility
• Input Type: LVTTL — maintains signal interface compatibility
• Output Type: LVTTL — ensures output signal compatibility with downstream circuits
• PLL: Yes with Bypass — preserves clock generation and bypass functionality
• Number of Circuits: 1 — maintains single-channel operation

Functional Parameters Allowing Variation:

• Frequency - Max: Substitute parts may exceed the original 133.3MHz specification, provided they meet or exceed this minimum requirement
• Ratio - Input:Output: Substitute parts may differ from 1:8, as long as the application can accommodate the alternative ratio
• Operating Temperature: Substitute parts may have extended temperature ranges beyond 0°C ~ 70°C

The Texas Instruments CDCVF25081D and CDCVF25081DR are qualified substitutes. Both maintain identical package, mounting, voltage supply, input/output signal types, and PLL functionality. These parts exceed the frequency specification (200MHz vs. 133.3MHz) and feature extended operating temperature ranges (-40°C ~ 85°C), providing enhanced performance margins and broader environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 23S08-2DCG8 is obsolete, while both CDCVF25081D and CDCVF25081DR are active products from Texas Instruments. Active product status ensures ongoing availability, technical support, and compliance with current regulatory standards.

Compliance & Certifications: Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original part's compliance status is not specified, making the substitutes preferable for new designs and production requiring documented compliance.

Packaging & Availability: CDCVF25081D is supplied in Tube packaging. CDCVF25081DR is supplied in Cut Tape (CT) and Digi-Reel format, suitable for high-volume automated assembly. Selection between these variants depends on procurement volume and assembly process requirements.

Performance Enhancement: Both substitutes operate at 200MHz maximum frequency, exceeding the original 133.3MHz specification by 50%, providing additional performance margin. Extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C) accommodates broader environmental conditions.

Frequently Asked Questions (FAQ)

Q: Are CDCVF25081D and CDCVF25081DR functionally identical? A: Both parts are functionally identical. The difference is packaging format: CDCVF25081D uses Tube packaging, while CDCVF25081DR uses Cut Tape and Digi-Reel format. Selection depends on procurement volume and assembly automation requirements.

Q: Will the 2:8 input-to-output ratio of the substitute parts work in place of the 1:8 ratio? A: The input-to-output ratio difference must be evaluated against specific application requirements. The substitute parts' 2:8 ratio differs from the original 1:8 ratio. Circuit design and clock frequency requirements must be verified to confirm compatibility.

Q: Are the substitute parts pin-compatible with the 23S08-2DCG8? A: Both substitute parts use the identical 16-SOIC (0.154", 3.90mm Width) package, ensuring PCB footprint compatibility. Pin-level compatibility must be verified against detailed pinout documentation for both the original and substitute parts.

Q: What is the advantage of the extended operating temperature range? A: The substitute parts operate from -40°C to 85°C, compared to the original 0°C to 70°C range. This extended range accommodates industrial and automotive applications requiring operation in wider temperature environments.

Q: Are the substitute parts suitable for new production designs? A: Yes. Both CDCVF25081D and CDCVF25081DR are active products with ROHS3 compliance and REACH compliance documentation, making them suitable for new production designs requiring current regulatory compliance.

Q: What is the significance of MSL 1 (Unlimited) rating? A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management.
