CDCLVP2108RGZR Equivalent & Substitute Parts

Part Overview

The CDCLVP2108RGZR is a Clock Fanout Buffer (Distribution) IC manufactured by Texas Instruments, designed for high-speed clock distribution applications. This 1:16 differential clock buffer operates at frequencies up to 2 GHz and is housed in a 48-VFQFN Exposed Pad package. The device is currently in active production status with 3878 units in stock. Alternative models may be required due to inventory constraints, application-specific output requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCLVP2108RGZR is determined by the following critical parameters: input:output ratio, maximum frequency, supply voltage range, operating temperature range, package type, input/output signal levels, and regulatory compliance status.

Parametric equivalents maintain identical specifications across all electrical and mechanical parameters. Manufacturer-recommended alternatives may differ in input:output ratio or supply voltage range while maintaining compatibility within the application's operational envelope.

The following substitution categories apply:

Parametric Equivalent (Direct Replacement): Identical input:output ratio (1:16), frequency (2 GHz), voltage supply (2.375V ~ 3.6V), package (48-VFQFN), and all signal level specifications.

Manufacturer-Recommended Alternative: Same frequency (2 GHz) and package footprint (48-VFQFN), but with reduced input:output ratio (1:8) and slightly narrower supply voltage range (2.375V ~ 3.465V). Suitable for applications requiring fewer output channels.

Parameter Comparison

Engineering Selection Recommendations

CDCLVP2108RGZT is the direct parametric equivalent to CDCLVP2108RGZR. Both devices are manufactured by Texas Instruments with identical electrical specifications, package dimensions, and compliance certifications. Selection between these two should be based on inventory availability and lead time requirements.

8SLVP2108ANLGI/W and 8SLVP2108ANLGI8 are manufacturer-recommended alternatives from Renesas Electronics Corporation. These devices maintain the same 2 GHz maximum frequency, 48-VFQFN package footprint, and ROHS3 compliance. The primary difference is the reduced input:output ratio of 1:8 compared to the 1:16 ratio of the main part. These alternatives are suitable for applications requiring eight output channels instead of sixteen. The supply voltage range is slightly narrower (2.375V ~ 3.465V versus 2.375V ~ 3.6V), which must be verified against application requirements. Both Renesas alternatives support CML input in addition to the standard LVCMOS, LVDS, LVPECL, and LVTTL inputs.

All substitute parts maintain active product status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can CDCLVP2108RGZT be used as a direct replacement for CDCLVP2108RGZR?

A: Yes. CDCLVP2108RGZT is a parametric equivalent with identical electrical and mechanical specifications. Both are Texas Instruments products in the same package with the same input:output ratio, frequency rating, and supply voltage range.

Q: What is the key difference between the Texas Instruments and Renesas alternatives?

A: The Renesas 8SLVP2108ANLGI/W and 8SLVP2108ANLGI8 devices provide 1:8 output distribution instead of 1:16. This means they support eight output channels rather than sixteen. The maximum frequency and package remain the same at 2 GHz and 48-VFQFN respectively.

Q: Can I use the Renesas 8SLVP2108ANLGI8 if my application requires 16 output channels?

A: No. The Renesas device provides only 8 output channels. If your circuit design requires 16 independent clock outputs, the CDCLVP2108RGZR or CDCLVP2108RGZT must be used.

Q: Are there supply voltage compatibility concerns with the Renesas alternatives?

A: The Renesas devices operate within 2.375V ~ 3.465V, which is narrower than the Texas Instruments range of 2.375V ~ 3.6V. If your application requires operation above 3.465V, the Texas Instruments parts must be used.

Q: Do all substitute parts support the same input signal levels?

A: The Texas Instruments CDCLVP2108RGZR and CDCLVP2108RGZT support LVCMOS, LVDS, LVPECL, and LVTTL inputs. The Renesas alternatives additionally support CML input. All devices output LVPECL signals.

Q: Are the package dimensions identical across all parts?

A: All parts use the 48-VFQFN Exposed Pad package with 7x7 mm footprint. The supplier device package designation differs slightly (48-VQFN for Texas Instruments, 48-VFQFPN for Renesas), but the physical dimensions and pin layout are compatible.

Q: What is the moisture sensitivity level for these parts?

A: All parts carry MSL rating 3 with a 168-hour floor life. Standard moisture control procedures during storage and handling apply.
