CDC7005RGZR Equivalent & Substitute Parts

Part Overview

The CDC7005RGZR is a Clock Synchronizer and Jitter Cleaner IC manufactured by Texas Instruments, operating at a maximum frequency of 800MHz. This device is classified as obsolete, which necessitates identification of active alternative components that maintain electrical and mechanical compatibility for system integration.

The CDC7005RGZR is packaged in a 48-VFQFN Exposed Pad configuration and serves applications requiring clock synchronization with jitter reduction capabilities. Due to its obsolete status, equivalent and substitute parts are required for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDC7005RGZR is determined by strict equivalence across the following electrical and mechanical parameters:

Core Electrical Parameters:

• Frequency maximum: 800MHz
• Input signal types: LVCMOS, LVPECL
• Output signal type: LVPECL
• Input:Output ratio: 2:5
• Differential input and output capability: Yes/Yes
• Supply voltage range: 3V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Number of circuits: 1

Mechanical and Compliance Parameters:

• Mounting type: Surface Mount
• RoHS3 compliance
• MSL rating: 3 (168 Hours)
• Base product number: CDC7005

Substitute parts are grouped into two categories based on packaging configuration:

Category 1 - Parametric Equivalent (Same Package): CDC7005RGZT maintains identical electrical specifications and the same 48-VFQFN Exposed Pad package, differing only in tape and reel packaging format and active product status.

Category 2 - Functional Equivalent (Alternative Package): CDC7005ZVAR maintains all electrical specifications but uses a 64-LFBGA package, requiring PCB layout and assembly process modifications.

Parameter Comparison

Engineering Selection Recommendations

CDC7005RGZT is the primary substitute for CDC7005RGZR. Both components share identical electrical specifications, package configuration (48-VFQFN Exposed Pad), and mechanical dimensions. The CDC7005RGZT is currently in active production status, ensuring long-term availability and supply chain continuity. This substitute requires no PCB layout modifications and maintains full functional compatibility. Both components are ROHS3 compliant with identical MSL ratings.

CDC7005ZVAR is a functional equivalent that maintains all electrical specifications but uses a 64-LFBGA package instead of the 48-VFQFN configuration. Selection of this substitute requires PCB redesign to accommodate the different package footprint and ball grid array layout. The CDC7005ZVAR is also in active production status and maintains ROHS3 compliance and identical MSL ratings. This option is suitable for new designs where PCB layout modifications are feasible.

Both substitute parts are manufactured by Texas Instruments under the CDC7005 base product number, ensuring design continuity and functional equivalence to the obsolete CDC7005RGZR.

Frequently Asked Questions (FAQ)

Q: Can CDC7005RGZT be used as a direct replacement for CDC7005RGZR without PCB modifications?

A: Yes. The CDC7005RGZT is a parametric equivalent with identical electrical specifications and the same 48-VFQFN Exposed Pad package. No PCB layout changes are required. The only difference is the packaging format (Tape & Reel versus bulk) and active product status.

Q: What are the key differences between CDC7005RGZT and CDC7005ZVAR?

A: Both maintain identical electrical specifications and operating parameters. The primary difference is packaging: CDC7005RGZT uses a 48-VFQFN Exposed Pad (7x7mm), while CDC7005ZVAR uses a 64-LFBGA (8x8mm). PCB redesign is required to use CDC7005ZVAR.

Q: Are all three parts (CDC7005RGZR, CDC7005RGZT, CDC7005ZVAR) ROHS3 compliant?

A: Yes. All three components are ROHS3 compliant with identical Moisture Sensitivity Level ratings of 3 (168 Hours).

Q: What is the supply voltage range for these clock synchronizer ICs?

A: The supply voltage range is 3V to 3.6V for all three parts.

Q: Can CDC7005ZVAR be used in existing designs without redesign?

A: No. The CDC7005ZVAR uses a 64-LFBGA package, which has different pin assignments and footprint dimensions compared to the 48-VFQFN package used in CDC7005RGZR and CDC7005RGZT. PCB layout and assembly process modifications are required.

Q: What is the maximum operating frequency for these clock synchronizer ICs?

A: The maximum operating frequency is 800MHz for all three components.

Q: Are the input and output signal types identical across all three parts?

A: Yes. All three parts accept LVCMOS and LVPECL inputs and provide LVPECL outputs with a 2:5 input-to-output ratio and differential signaling capability.
