CDCLVP1204RGTR Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The CDCLVP1204RGTR is an active clock fanout buffer and distribution multiplexer IC manufactured by Texas Instruments. This device functions as a 2:4 clock buffer with a maximum frequency of 2 GHz, designed for high-speed signal distribution in digital systems. The part accepts multiple input signal types (LVCMOS, LVDS, LVPECL, LVTTL) and outputs LVPECL signals. With an active product status and full RoHS3 compliance, substitute parts are identified based on matching electrical specifications, package compatibility, and operational parameters to support procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDCLVP1204RGTR are identified based on strict parameter matching across the following critical criteria:

Electrical Compatibility Parameters:

• Input:Output ratio of 2:4
• Maximum frequency of 2 GHz
• Output signal type of LVPECL
• Supply voltage range compatibility (2.375V minimum and 3.6V or higher maximum)
• Operating temperature range of -40°C to 85°C

Physical & Packaging Parameters:

• 16-pin VFQFN package with exposed pad
• 3x3mm supplier device package footprint
• Surface mount mounting type

Compliance & Certification Parameters:

• RoHS3 compliance status
• Active product status

Substitutes are grouped into two categories: parametric equivalents from the same manufacturer (Texas Instruments) and manufacturer-recommended alternatives from Renesas Electronics Corporation. All identified substitutes maintain identical or compatible electrical specifications and package dimensions, ensuring direct functional replacement capability.

Parameter Comparison

Engineering Selection Recommendations

Texas Instruments CDCLVP1204RGTT: This part is a parametric equivalent to the CDCLVP1204RGTR from the same manufacturer. Both devices share identical electrical specifications, package dimensions, and compliance certifications. The CDCLVP1204RGTT is suitable for direct substitution when supply constraints affect the primary part number. Both parts maintain RoHS3 compliance and MSL rating of 2 (1 Year), indicating equivalent moisture handling requirements.

Renesas Electronics 8SLVP1204ANLGI/W and 8SLVP1204ANLGI8: These parts are manufacturer-recommended alternatives that meet all critical electrical and physical parameters. Both Renesas parts accept CML, LVDS, and LVPECL input signals (note: LVCMOS and LVTTL inputs are not supported), output LVPECL signals, and operate at 2 GHz maximum frequency with 2:4 ratio configuration. Supply voltage range extends to 3.63V (compared to 3.6V for Texas Instruments parts). Both Renesas parts carry RoHS3 compliance and active product status. The MSL rating of 3 (168 Hours) for Renesas parts indicates a shorter moisture sensitivity window compared to the Texas Instruments MSL rating of 2 (1 Year), requiring attention to storage and handling conditions.

All four parts are active products with full RoHS3 compliance and REACH unaffected status, supporting long-term design and procurement viability.

Frequently Asked Questions (FAQ)

Q: Can the Renesas 8SLVP1204ANLGI/W or 8SLVP1204ANLGI8 be used as direct replacements for the CDCLVP1204RGTR?

A: The Renesas parts are functionally compatible for applications using LVDS or LVPECL input signals. However, if your design requires LVCMOS or LVTTL input support, the Renesas alternatives do not support these input types. Verify your input signal requirements before substitution.

Q: What is the difference between CDCLVP1204RGTR and CDCLVP1204RGTT?

A: Both parts are Texas Instruments products with identical electrical specifications, package dimensions, and compliance ratings. The difference lies in packaging format or tape reel configuration. Both are suitable for direct substitution.

Q: Are there any moisture sensitivity differences between the Texas Instruments and Renesas parts?

A: Yes. Texas Instruments parts (CDCLVP1204RGTR and CDCLVP1204RGTT) have MSL rating 2 (1 Year), allowing extended storage at controlled humidity. Renesas parts (8SLVP1204ANLGI/W and 8SLVP1204ANLGI8) have MSL rating 3 (168 Hours), requiring more stringent moisture control and shorter storage windows. Plan component handling and storage accordingly.

Q: Do all substitute parts support the same supply voltage range?

A: The Texas Instruments parts support 2.375V to 3.6V. The Renesas parts support 2.375V to 3.63V. Both ranges are compatible for standard 3.3V supply applications. Verify your specific supply voltage requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. All four parts (CDCLVP1204RGTR, CDCLVP1204RGTT, 8SLVP1204ANLGI/W, and 8SLVP1204ANLGI8) are RoHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: Can these parts be used interchangeably in PCB layouts?

A: Yes. All parts use the same 16-VFQFN package with 3x3mm footprint and exposed pad configuration, ensuring identical PCB layout compatibility and no redesign required for physical substitution.
