Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDCF5801ADBQRG4 is determined by strict equivalence across the following critical parameters:

• Frequency Performance: Maximum operating frequency of 280MHz
• Signal Standards: Support for HSTL, LVPECL, LVTTL input and HSTL, LVDS, LVPECL, LVTTL, SSTL output
• Functional Architecture: PLL Multiplier/Divider with 1:1 input-to-output ratio
• Supply Voltage: 3V to 3.6V operating range
• Temperature Range: -40°C to 85°C
• Package Specification: 24-SSOP (0.154", 3.90mm Width) surface mount
• Compliance: ROHS3 compliance and MSL 2 rating

The CDCF5801DBQR meets all these parameters and is identified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The CDCF5801DBQR serves as a direct parametric equivalent to the CDCF5801ADBQRG4. Both parts share identical electrical specifications, frequency performance, signal standard support, and package configuration. The primary distinction is product status: the ADBQRG4 is discontinued, while the DBQR is marked as not for new designs. Both maintain ROHS3 compliance and equivalent moisture sensitivity ratings.

For applications requiring the CDCF5801ADBQRG4, the CDCF5801DBQR provides functional and electrical compatibility. Packaging differs only in format (bulk versus tape and reel), which does not affect electrical performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the CDCF5801DBQR directly replace the CDCF5801ADBQRG4 in existing designs?

A: Yes. Both parts are electrically and functionally identical across all specified parameters including frequency, signal standards, supply voltage, temperature range, and package dimensions. The 24-SSOP package footprint is identical, enabling direct PCB substitution.

Q: What is the difference between the ADBQRG4 and DBQR part numbers?

A: The suffix differences indicate packaging format. The ADBQRG4 is supplied in bulk packaging, while the DBQR is supplied in tape and reel format. Electrical specifications and performance are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical MSL 2 ratings. Regulatory and environmental compliance is equivalent.

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

A: The CDCF5801ADBQRG4 is discontinued at DiGi Electronics, indicating no further procurement availability through standard channels. The CDCF5801DBQR is marked as not for new designs, indicating limited availability and potential future discontinuation. For new system designs, alternative PLL multiplier/divider solutions from current product lines should be evaluated.

Q: Are the pin configurations identical between these parts?

A: Yes. Both parts use the 24-SSOP package with identical pin assignments and signal definitions, ensuring direct compatibility at the board level.
