Key Parameters

Substitute Part Grouping Explanation

The CDCF5801DBQR can be substituted with the CDCF5801ADBQR based on the following criteria:

Matching Parameters:

• Identical PLL Multiplier/Divider functionality
• Same maximum frequency specification (280MHz)
• Identical input standards (HSTL, LVPECL, LVTTL)
• Identical output standards (HSTL, LVDS, LVPECL, LVTTL, SSTL)
• Same number of circuits (1)
• Identical input:output ratio (1:1)
• Identical differential input:output configuration (No/Yes)
• Same supply voltage range (3V ~ 3.6V)
• Identical operating temperature range (-40°C ~ 85°C)
• Same package type (24-SSOP with 0.154", 3.90mm Width)
• Same mounting type (Surface Mount)
• Identical RoHS and REACH compliance status
• Same moisture sensitivity level (MSL 2, 1 Year)

The substitution is valid because all electrical and mechanical parameters are identical between the main part and the substitute.

Parameter Comparison

Engineering Selection Recommendations

The CDCF5801ADBQR is the direct substitute for the CDCF5801DBQR. The primary distinction between these parts is product status: the CDCF5801DBQR is classified as Not For New Designs, while the CDCF5801ADBQR maintains Active status. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The CDCF5801ADBQR is the appropriate selection for new designs and ongoing production where the CDCF5801DBQR is currently deployed. All electrical specifications, package dimensions, and compliance certifications are identical, ensuring direct functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can CDCF5801ADBQR directly replace CDCF5801DBQR in existing designs?

A: Yes. All electrical parameters, signal standards, frequency specifications, supply voltage requirements, operating temperature range, and package dimensions are identical. The parts are pin-compatible and functionally equivalent.

Q: What is the significance of the product status difference?

A: The CDCF5801DBQR is marked Not For New Designs, indicating Texas Instruments no longer recommends it for new applications. The CDCF5801ADBQR maintains Active status and is the current production equivalent. For legacy system support, the CDCF5801DBQR remains functional; for new designs, the CDCF5801ADBQR is the specified choice.

Q: Are there any package or mounting differences?

A: No. Both parts use the 24-SSOP package with identical dimensions (0.154", 3.90mm Width) and surface mount mounting type. PCB layouts and assembly processes require no modification.

Q: Do both parts support the same signal standards?

A: Yes. Both parts support identical input standards (HSTL, LVPECL, LVTTL) and output standards (HSTL, LVDS, LVPECL, LVTTL, SSTL), with the same 1:1 input:output ratio and differential configuration.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and have identical moisture sensitivity levels (MSL 2, 1 Year). Regulatory and environmental compliance requirements are met by both parts.
