CDCLVD1213RGTR Equivalent & Substitute Parts

Part Overview

The CDCLVD1213RGTR is an active clock fanout buffer and distribution IC manufactured by Texas Instruments, designed for high-speed clock signal distribution applications. This device functions as a 1:4 clock buffer operating at frequencies up to 800 MHz, accepting CML, LVDS, or LVPECL input signals and providing LVDS output. The part is classified as Active status and is ROHS3 compliant, making it suitable for modern electronic applications requiring reliable clock distribution in high-speed digital systems.

Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or packaging format requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

The CDCLVD1213RGTR and its substitute CDCLVD1213RGTT share an identical base product number (CDCLVD1213) and are functionally equivalent clock distribution ICs. Substitution between these parts is valid based on the following criteria:

Critical Parameters for Substitution:

• Ratio - Input:Output: 1:4 (identical)
• Frequency - Max: 800 MHz (identical)
• Input Signal Type: CML, LVDS, LVPECL (identical)
• Output Signal Type: LVDS (identical)
• Voltage - Supply: 2.375V ~ 2.625V (identical)
• Operating Temperature Range: -40°C ~ 85°C (identical)
• Package / Case: 16-VFQFN Exposed Pad (identical)
• Mounting Type: Surface Mount (identical)

The primary difference between these parts is the packaging format: CDCLVD1213RGTR is supplied in standard packaging, while CDCLVD1213RGTT is supplied in Tape & Reel (TR) format. Both parts maintain identical electrical specifications and physical package dimensions, allowing direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both CDCLVD1213RGTR and CDCLVD1213RGTT are Active status products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and procurement requirements:

CDCLVD1213RGTR is appropriate for applications requiring standard packaging format with lower volume requirements or when individual component handling is preferred.

CDCLVD1213RGTT is appropriate for high-volume production environments where Tape & Reel packaging provides automated assembly line compatibility and cost efficiency.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for modern electronic applications. The MSL rating of 2 (1 Year) applies to both variants, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can CDCLVD1213RGTT be used as a direct replacement for CDCLVD1213RGTR in circuit designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. CDCLVD1213RGTT uses Tape & Reel format while CDCLVD1213RGTR uses standard packaging. Circuit performance and PCB footprint remain unchanged.

Q: What is the significance of the packaging difference between these two part numbers?

A: Packaging format affects procurement and assembly processes. Tape & Reel (TR) format is optimized for automated pick-and-place assembly in high-volume manufacturing. Standard packaging is suitable for lower volumes or manual assembly. Electrical specifications are identical.

Q: Are there any compatibility concerns when substituting between CDCLVD1213RGTR and CDCLVD1213RGTT?

A: No compatibility concerns exist. Both parts use the same 16-VFQFN Exposed Pad package with 3x3 mm dimensions. PCB footprints, solder pad layouts, and electrical interfaces are identical.

Q: What input and output signal types does this clock buffer support?

A: The CDCLVD1213 accepts CML, LVDS, or LVPECL input signals and provides LVDS output. The 1:4 distribution ratio allows a single input clock to be fanned out to four independent LVDS outputs at frequencies up to 800 MHz.

Q: What are the supply voltage requirements for these parts?

A: Both CDCLVD1213RGTR and CDCLVD1213RGTT require a supply voltage of 2.375V to 2.625V. This narrow voltage range is typical for low-voltage differential signaling (LVDS) applications and requires stable power supply regulation.

Q: Are these parts suitable for industrial temperature range applications?

A: Both parts operate across -40°C to 85°C, which covers commercial and extended industrial temperature ranges. For applications requiring wider temperature ranges, alternative products from Texas Instruments may be necessary.
