CDCLVP2104RHDR Equivalent & Substitute Parts

Part Overview

The CDCLVP2104RHDR is a Clock Fanout Buffer (Distribution) IC manufactured by Texas Instruments, designed for high-speed clock distribution applications. This 2:8 differential fanout buffer operates at frequencies up to 2 GHz and supports multiple input standards (LVCMOS, LVDS, LVPECL, LVTTL) with LVPECL output. The device is packaged in a 28-VFQFN Exposed Pad surface mount package and is currently in active production status with ROHS3 compliance. Equivalent and substitute parts are identified based on matching electrical performance parameters, package compatibility, and functional specifications that allow direct or near-direct replacement in clock distribution circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDCLVP2104RHDR are identified based on the following critical parameters that determine functional compatibility:

Parametric Equivalent Classification: Parts that maintain identical or functionally equivalent specifications across all electrical and mechanical parameters, allowing direct replacement without circuit modification.

Key Substitution Criteria:

• Frequency maximum rating of 2 GHz or higher
• Supply voltage range compatibility (2.375V ~ 3.6V or subset thereof)
• Operating temperature range of -40°C ~ 85°C or wider
• LVPECL output capability
• Surface mount package with 28-pin VFQFN or compatible pinout
• Active product status and current manufacturing availability
• ROHS3 compliance and equivalent regulatory certifications

The CDCLVP2104RHDT (Texas Instruments, Cut Tape packaging) qualifies as a parametric equivalent, differing only in packaging format (Cut Tape vs. Tape & Reel). The 8SLVP2104ANBGI8 (Renesas Electronics Corporation) is classified as a manufacturer-recommended alternative with functional differences in input/output ratio (1:4 vs. 2:8) and supply voltage specifications, requiring circuit-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

CDCLVP2104RHDT: This part is a direct parametric equivalent to the CDCLVP2104RHDR. Both devices share identical electrical specifications, frequency ratings, supply voltage ranges, and package dimensions. The only distinction is packaging format: CDCLVP2104RHDT is supplied in Cut Tape format rather than Tape & Reel. Selection between these two parts depends solely on procurement and assembly line requirements. Both maintain active product status and ROHS3 compliance.

8SLVP2104ANBGI8: This Renesas Electronics Corporation device is a manufacturer-recommended alternative with functional differences that require evaluation against specific circuit requirements. The 1:4 input-to-output ratio differs from the 2:8 ratio of the main part, resulting in different fanout capabilities. Supply voltage specifications are narrower and defined in two discrete ranges (2.375V ~ 2.625V and 3.135V ~ 3.465V) rather than a continuous range. The device offers improved moisture sensitivity (MSL 1 vs. MSL 3), indicating superior moisture resistance. Package designation differs (28-WFQFN vs. 28-VFQFN), though both are 5x5mm surface mount packages. Selection of this part requires confirmation that the 1:4 fanout ratio and discrete voltage ranges align with circuit design specifications.

Frequently Asked Questions (FAQ)

Q: Can CDCLVP2104RHDT be used as a direct replacement for CDCLVP2104RHDR?

A: Yes. The CDCLVP2104RHDT is a parametric equivalent with identical electrical and functional specifications. The difference is packaging format only (Cut Tape vs. Tape & Reel). Direct substitution is appropriate for applications where packaging format does not constrain assembly processes.

Q: What are the key differences between CDCLVP2104RHDR and 8SLVP2104ANBGI8?

A: The primary differences are: (1) Input-to-output ratio is 2:8 versus 1:4, affecting fanout capability; (2) Supply voltage ranges differ, with 8SLVP2104ANBGI8 specified in two discrete bands rather than a continuous range; (3) Manufacturer differs (Texas Instruments vs. Renesas Electronics); (4) Package designation differs (28-VFQFN vs. 28-WFQFN); (5) Moisture sensitivity is superior in the Renesas part (MSL 1 vs. MSL 3).

Q: Is the 8SLVP2104ANBGI8 suitable for applications requiring 2:8 fanout?

A: No. The 8SLVP2104ANBGI8 provides 1:4 fanout, which is insufficient for applications requiring 2:8 distribution. This part is suitable only for applications with 1:4 fanout requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. CDCLVP2104RHDR, CDCLVP2104RHDT, and 8SLVP2104ANBGI8 are all ROHS3 compliant and REACH unaffected.

Q: What is the significance of MSL rating differences?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions before soldering. CDCLVP2104RHDR and CDCLVP2104RHDT have MSL 3 (168 hours maximum), while 8SLVP2104ANBGI8 has MSL 1 (unlimited exposure). Higher MSL ratings provide greater flexibility in storage and handling but do not affect electrical performance.

Q: Can the supply voltage ranges of 8SLVP2104ANBGI8 be treated as equivalent to CDCLVP2104RHDR?

A: No. The 8SLVP2104ANBGI8 supply voltage is specified as two discrete ranges (2.375V ~ 2.625V and 3.135V ~ 3.465V), while CDCLVP2104RHDR operates across a continuous range (2.375V ~ 3.6V). Applications requiring operation in the 2.625V ~ 3.135V window cannot use the Renesas part.
