CDCLVP1216RGZR Equivalent & Substitute Parts

Part Overview

The CDCLVP1216RGZR is a Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Texas Instruments, designed for high-speed clock distribution applications. This 2:16 fanout buffer operates at frequencies up to 2 GHz and is housed in a 48-VFQFN Exposed Pad surface mount package. The device is currently in active production status and maintains full RoHS3 compliance. Substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits equivalent functionality within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDCLVP1216RGZR are qualified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Input:Output Ratio: 2:16 (exact match required)
• Maximum Frequency: 2 GHz (minimum requirement)
• Differential Input/Output: Yes/Yes (signal type compatibility)
• Supply Voltage Range: Overlapping operational window
• Package Type: 48-VFQFN Exposed Pad (mechanical and thermal compatibility)
• Operating Temperature Range: -40°C ~ 85°C (environmental compatibility)
• Surface Mount Configuration: Required for PCB assembly compatibility

Substitutes are grouped into two categories: parametric equivalents (identical specifications from the same manufacturer) and manufacturer-recommended alternatives (functionally equivalent parts from different manufacturers with minor specification variations within acceptable engineering tolerances).

Parameter Comparison

Engineering Selection Recommendations

CDCLVP1216RGZT (Texas Instruments): This part is a parametric equivalent to the CDCLVP1216RGZR, differing only in packaging format (Cut Tape & Digi-Reel versus standard packaging). Both parts share identical electrical specifications, supply voltage range, operating temperature range, and RoHS3 compliance status. Selection of this substitute is appropriate when the original part number is unavailable and packaging format flexibility exists in procurement workflows.

PI6C5912016ZDIEX (Diodes Incorporated): This manufacturer-recommended alternative meets all critical functional requirements with the following considerations: the supply voltage range is slightly narrower (2.375V ~ 3.465V versus 2.375V ~ 3.6V), and the Moisture Sensitivity Level is superior (MSL 1 Unlimited versus MSL 3 168 Hours). Both parts maintain identical 2:16 ratio, 2 GHz maximum frequency, LVPECL output, and operating temperature specifications. The package designation differs slightly (48-TQFN versus 48-VQFN), though both are 7x7mm footprints with exposed pads. This substitute is suitable for applications where the reduced supply voltage ceiling does not conflict with system design requirements and where improved moisture handling is beneficial.

Frequently Asked Questions (FAQ)

Q: Can CDCLVP1216RGZT be used as a direct replacement for CDCLVP1216RGZR?

A: Yes. Both parts are manufactured by Texas Instruments and share identical electrical specifications, including 2:16 fanout ratio, 2 GHz maximum frequency, 2.375V ~ 3.6V supply voltage range, and -40°C ~ 85°C operating temperature. The difference is packaging format only. Verify that your procurement and assembly processes accommodate the packaging type (Cut Tape & Digi-Reel).

Q: What are the key differences between the Texas Instruments CDCLVP1216RGZR and the Diodes Incorporated PI6C5912016ZDIEX?

A: Both parts provide 2:16 fanout buffering at 2 GHz with LVPECL output and identical operating temperature range. The PI6C5912016ZDIEX has a narrower supply voltage range (2.375V ~ 3.465V) and superior moisture sensitivity rating (MSL 1 Unlimited). The package designation differs slightly (48-TQFN versus 48-VQFN), though both are 7x7mm surface mount packages with exposed pads. Confirm that your system supply voltage does not exceed 3.465V before selecting this substitute.

Q: Are the 48-VQFN and 48-TQFN packages mechanically compatible?

A: Both packages are 7x7mm surface mount configurations with exposed pads and 48-pin counts. Mechanical footprint compatibility exists for PCB layout purposes. Consult the detailed package drawings from each manufacturer to verify thermal pad dimensions and pin placement specifications for your specific assembly process.

Q: Do all three parts meet the same compliance requirements?

A: Yes. All three parts (CDCLVP1216RGZR, CDCLVP1216RGZT, and PI6C5912016ZDIEX) are ROHS3 compliant and REACH unaffected. The CDCLVP1216RGZR and CDCLVP1216RGZT share identical MSL ratings (3, 168 Hours). The PI6C5912016ZDIEX has a superior MSL rating (1, Unlimited), which may provide advantages in high-humidity storage or assembly environments.

Q: What input signal types are supported by each substitute?

A: The CDCLVP1216RGZR and CDCLVP1216RGZT support LVCMOS, LVDS, LVPECL, and LVTTL inputs. The PI6C5912016ZDIEX supports differential or single-ended inputs. Verify that your clock source signal type is compatible with the selected part before implementation.
