CDCLVP1208RHDR Equivalent & Substitute Parts

Part Overview

The CDCLVP1208RHDR is an active Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Texas Instruments, designed for high-speed clock distribution applications. This 2:8 clock buffer operates at frequencies up to 2 GHz and supports multiple input standards (LVCMOS, LVDS, LVPECL, LVTTL) with LVPECL output. The device is housed in a 28-VFQFN Exposed Pad surface mount package and is currently in active production status with ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter ranges, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDCLVP1208RHDR are qualified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Input:Output Ratio: 2:8 (mandatory match)
• Maximum Frequency: 2 GHz (mandatory match)
• Output Standard: LVPECL (mandatory match)
• Supply Voltage Range: Overlapping or compatible range
• Operating Temperature Range: -40°C ~ 85°C (mandatory match)
• Package Type: 28-pin VFQFN or equivalent footprint
• Surface Mount Configuration: Required

Substitution Categories:

Parametric Equivalent: Parts with identical electrical specifications and package compatibility, differing only in packaging format (Cut Tape vs. Digi-Reel) or minor supplier designation variations.

Manufacturer Recommended Equivalent: Parts from alternative manufacturers meeting all critical electrical parameters and operating conditions, with compatible package footprints and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

CDCLVP1208RHDT (Texas Instruments): This part is a parametric equivalent to the CDCLVP1208RHDR, maintaining identical electrical specifications, supply voltage range, operating temperature range, and package configuration. Both parts are manufactured by Texas Instruments and carry ROHS3 compliance with MSL 3 rating. Selection between these two variants is determined by packaging format requirements (Cut Tape vs. Digi-Reel) and inventory availability. No functional differences exist between these parts.

8SLVP1208ANBGI8 (Renesas Electronics Corporation): This part qualifies as a manufacturer-recommended equivalent, meeting all critical electrical parameters including 2:8 ratio, 2 GHz maximum frequency, LVPECL output, and -40°C to 85°C operating temperature range. The supply voltage range is slightly narrower (2.375V ~ 3.465V versus 2.375V ~ 3.6V), which remains compatible with standard 3.3V supply applications. The package footprint is mechanically compatible (28-pin WFQFN versus VFQFN, both 5x5mm). The Renesas part offers superior moisture handling with MSL 1 (Unlimited) rating compared to MSL 3. Input standard support differs slightly (CML, LVDS, LVPECL versus LVCMOS, LVDS, LVPECL, LVTTL); applications requiring LVCMOS or LVTTL input must remain with Texas Instruments variants. All parts maintain ROHS3 compliance and active production status.

Frequently Asked Questions (FAQ)

Q: Can CDCLVP1208RHDT be used as a direct replacement for CDCLVP1208RHDR?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, supply voltage range (2.375V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and 28-VFQFN package configuration. The parts differ only in packaging format designation. No circuit modifications are required.

Q: What are the key differences between the Texas Instruments and Renesas equivalents?

A: The Renesas 8SLVP1208ANBGI8 maintains the same 2:8 ratio, 2 GHz frequency, LVPECL output, and operating temperature range. The supply voltage range is narrower (2.375V ~ 3.465V). Input standard support differs: Renesas supports CML, LVDS, and LVPECL, while Texas Instruments supports LVCMOS, LVDS, LVPECL, and LVTTL. The Renesas part has superior moisture sensitivity (MSL 1 versus MSL 3). Package footprints are mechanically compatible (28-pin WFQFN versus VFQFN, both 5x5mm).

Q: Can the Renesas 8SLVP1208ANBGI8 replace the Texas Instruments part in all applications?

A: The Renesas part is suitable for applications using LVDS or LVPECL inputs. Applications requiring LVCMOS or LVTTL input support must use the Texas Instruments variants (CDCLVP1208RHDR or CDCLVP1208RHDT). Verify supply voltage requirements remain within the Renesas range of 2.375V ~ 3.465V.

Q: Are all three parts ROHS3 compliant?

A: Yes. CDCLVP1208RHDR, CDCLVP1208RHDT, and 8SLVP1208ANBGI8 are all ROHS3 compliant and suitable for applications with RoHS requirements.

Q: What is the significance of the MSL rating difference?

A: CDCLVP1208RHDR and CDCLVP1208RHDT carry MSL 3 (168 Hours), requiring controlled storage and handling conditions. The Renesas 8SLVP1208ANBGI8 carries MSL 1 (Unlimited), allowing indefinite storage without moisture control measures. MSL 1 provides operational flexibility in supply chain and storage environments.

Q: Are the package footprints identical between all three parts?

A: The Texas Instruments parts use 28-VFQFN (5x5mm) while the Renesas part uses 28-WFQFN (5x5mm). Both are 28-pin, 5x5mm exposed pad packages with compatible PCB footprints for direct substitution. Verify PCB layout compatibility with your design specifications.
