Equivalent & Substitute Parts for 23S08-2DCGI

Part Overview

The 23S08-2DCGI is a Clock Multiplier with Zero Delay Buffer IC manufactured by Renesas Electronics Corporation. This 16-SOIC surface mount device operates at a maximum frequency of 133.3MHz with a 1:8 input-to-output ratio and supports PLL with bypass functionality. The part is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 23S08-2DCGI is determined by compatibility across the following critical parameters:

Electrical Compatibility:

• Package type: 16-SOIC (0.154", 3.90mm Width) — identical pinout and footprint required
• Supply voltage range: 3V ~ 3.6V — must support the same operating voltage
• Input signal type: LVTTL — compatible input logic levels
• Output signal type: LVTTL — compatible output logic levels
• PLL with bypass functionality — required for functional equivalence
• Operating temperature range: -40°C ~ 85°C — must cover the same thermal envelope
• Number of circuits: 1 — single circuit configuration

Mechanical Compatibility:

• Surface mount technology — same mounting method
• 16-pin SOIC package — identical physical dimensions and pin count

The substitute parts CDCVF25081D and CDCVF25081DR, both manufactured by Texas Instruments, meet these compatibility criteria. While these parts operate at a higher maximum frequency (200MHz) and feature a different input-to-output ratio (2:8), they maintain electrical and mechanical compatibility within the specified parameters for the 23S08-2DCGI application.

Parameter Comparison

Engineering Selection Recommendations

CDCVF25081D and CDCVF25081DR Selection Basis:

Both Texas Instruments parts are active products with current manufacturing status, providing long-term availability and supply chain stability compared to the obsolete 23S08-2DCGI. Both parts maintain identical electrical operating parameters (supply voltage, temperature range, input/output logic levels, PLL with bypass) and physical compatibility (16-SOIC package, surface mount).

The CDCVF25081DR variant is supplied in Tape & Reel (TR) packaging, suitable for high-volume automated assembly operations. The CDCVF25081D is supplied in Tube packaging, appropriate for lower-volume or manual assembly scenarios.

Both substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements. The higher maximum frequency rating (200MHz) of the substitute parts provides operational margin above the 23S08-2DCGI specification (133.3MHz), ensuring compatibility with existing system timing requirements.

Frequently Asked Questions (FAQ)

Q: Can CDCVF25081D and CDCVF25081DR be used interchangeably with 23S08-2DCGI?

A: Yes, both parts are electrically and mechanically compatible. The primary difference is packaging format: CDCVF25081D uses Tube packaging, while CDCVF25081DR uses Tape & Reel packaging. Selection depends on assembly method and volume requirements.

Q: What is the difference between CDCVF25081D and CDCVF25081DR?

A: Both parts are functionally identical. CDCVF25081D is supplied in Tube packaging for manual or low-volume assembly. CDCVF25081DR is supplied in Cut Tape and Digi-Reel packaging for automated high-volume assembly operations.

Q: Why do the substitute parts have different input-to-output ratios (2:8 vs. 1:8)?

A: The input-to-output ratio difference reflects different internal multiplier configurations. Both parts maintain PLL with bypass functionality and operate within the same supply voltage and temperature ranges, ensuring functional compatibility in applications designed for the 23S08-2DCGI.

Q: Are the substitute parts pin-compatible with 23S08-2DCGI?

A: Yes. All three parts use the 16-SOIC (0.154", 3.90mm Width) package with identical pinout and footprint, enabling direct PCB-level substitution without layout modifications.

Q: What is the advantage of using CDCVF25081D or CDCVF25081DR over the obsolete 23S08-2DCGI?

A: The Texas Instruments parts are active products with guaranteed long-term availability, current manufacturing processes, and ROHS3 compliance. The 23S08-2DCGI is obsolete and subject to supply discontinuation.

Q: Do the substitute parts support the same operating temperature range?

A: Yes. Both CDCVF25081D and CDCVF25081DR operate across -40°C to 85°C, matching the 23S08-2DCGI specification.

Q: Are moisture sensitivity levels equivalent across all three parts?

A: Yes. All three parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
