CDCLVD1216RGZR Equivalent & Substitute Parts

Part Overview

The CDCLVD1216RGZR 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 a maximum frequency of 800 MHz and supports multiple input standards (LVCMOS, LVDS, LVPECL) with LVDS output. The device is housed in a 48-VFQFN Exposed Pad package and is currently in active production status. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDCLVD1216RGZR are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• Input:Output Ratio (2:16)
• Package Type (48-VFQFN Exposed Pad)
• Output Standard (LVDS)
• Operating Temperature Range (-40°C ~ 85°C)
• Mounting Type (Surface Mount)

Allowable Variation Parameters:

• Maximum Frequency (equal or higher)
• Supply Voltage Range (must encompass or match the original specification)
• Input Standards (may differ if functionally compatible)

Two substitute parts meet these criteria: CDCLVD1216RGZT (parametric equivalent from Texas Instruments) and PI6C5921516ZDIEX (manufacturer-recommended alternative from Diodes Incorporated).

Parameter Comparison

Engineering Selection Recommendations

CDCLVD1216RGZT (Texas Instruments - Parametric Equivalent)

This part is a direct parametric equivalent to the CDCLVD1216RGZR, differing only in packaging format (Cut Tape & Digi-Reel versus standard packaging). All electrical specifications, frequency ratings, supply voltage requirements, and temperature ranges are identical. Both parts maintain ROHS3 compliance and identical moisture sensitivity levels. This substitute is suitable for applications requiring identical performance specifications with alternative packaging or inventory availability.

PI6C5921516ZDIEX (Diodes Incorporated - Manufacturer-Recommended Alternative)

This part meets all critical substitution criteria with the following distinctions: it operates at a higher maximum frequency (1.5 GHz versus 800 MHz), supports a wider supply voltage range (2.375V ~ 3.465V), and features a lower moisture sensitivity level (MSL 1 versus MSL 3). The input standard specification differs (Differential or Single-Ended versus LVCMOS, LVDS, LVPECL), but both configurations support the required differential input capability. This substitute is suitable for applications where higher frequency headroom or improved moisture tolerance is beneficial, provided the wider supply voltage range is compatible with the system design.

All three parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can CDCLVD1216RGZT be used as a direct replacement for CDCLVD1216RGZR?

A: Yes. CDCLVD1216RGZT is a parametric equivalent with identical electrical specifications, frequency rating, supply voltage, and operating temperature range. The only difference is packaging format (Cut Tape & Digi-Reel). Pin configuration and functional performance are identical.

Q: What are the key differences between PI6C5921516ZDIEX and CDCLVD1216RGZR?

A: PI6C5921516ZDIEX operates at 1.5 GHz (versus 800 MHz), supports a wider supply voltage range (2.375V ~ 3.465V versus 2.375V ~ 2.625V), and has a lower moisture sensitivity level (MSL 1 versus MSL 3). Input standard specifications differ, but both support differential input operation. The 48-VFQFN package and 2:16 ratio are identical.

Q: Are all three parts pin-compatible?

A: CDCLVD1216RGZR and CDCLVD1216RGZT are fully pin-compatible. PI6C5921516ZDIEX shares the same 48-VFQFN package footprint and pin count, but functional pin assignments may differ. Verify input/output pin mapping against application schematics before substitution.

Q: Which substitute should I select for high-reliability applications?

A: PI6C5921516ZDIEX offers superior moisture tolerance (MSL 1 with unlimited shelf life versus MSL 3 with 168-hour limit), making it suitable for high-reliability or extended storage applications. CDCLVD1216RGZT maintains identical specifications to the original part and is appropriate when moisture sensitivity is not a limiting factor.

Q: Can PI6C5921516ZDIEX be used in applications designed for 800 MHz operation?

A: Yes. PI6C5921516ZDIEX operates at frequencies up to 1.5 GHz, which encompasses 800 MHz operation. The higher frequency capability does not prevent operation at lower frequencies. Verify that the wider supply voltage range (2.375V ~ 3.465V) is compatible with your system power distribution.

Q: What is the impact of different moisture sensitivity levels?

A: MSL 3 (CDCLVD1216RGZR and CDCLVD1216RGZT) requires storage at controlled humidity and has a 168-hour floor life after moisture exposure. MSL 1 (PI6C5921516ZDIEX) has unlimited shelf life and is more tolerant of storage condition variations. For high-volume manufacturing or extended inventory holding, MSL 1 reduces handling complexity.
