CDCF5801ADBQR PLL Multiplier/Divider IC Equivalent & Substitute Parts

Part Overview

The CDCF5801ADBQR is a PLL Multiplier/Divider integrated circuit manufactured by Texas Instruments, designed for clock and timing applications requiring frequency multiplication and division up to 280MHz. This device operates with supply voltages between 3V and 3.6V and supports multiple input and output signal standards including HSTL, LVPECL, LVTTL, HSTL, LVDS, and SSTL. The part is currently in Active product status with full RoHS3 compliance and Moisture Sensitivity Level 2 rating. Substitute parts become necessary when addressing inventory constraints, supply chain disruptions, or design revisions requiring alternative qualified components that maintain electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CDCF5801ADBQR is the preferred selection for new designs due to its Active product status, ensuring long-term availability and manufacturer support. The CDCF5801DBQR provides electrical and mechanical equivalence but carries a "Not For New Designs" designation, indicating that Texas Instruments has transitioned this variant away from active production cycles. Both parts maintain identical RoHS3 compliance and MSL 2 certifications, supporting equivalent environmental and reliability requirements. Selection between these parts should be based on design phase and supply chain requirements rather than functional capability, as all electrical parameters and package specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can CDCF5801DBQR be used as a direct replacement for CDCF5801ADBQR in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including frequency operation, supply voltage, temperature range, package configuration, and signal standards. The substitution is valid from a functional compatibility standpoint.

Q: What is the significance of the "Not For New Designs" status on CDCF5801DBQR?

A: This designation indicates that Texas Instruments has discontinued active promotion and development support for this part variant. While the part remains functionally equivalent, it should not be selected for new product designs. Existing designs using this part may continue operation without modification.

Q: Are the 24-SSOP packages for both parts identical?

A: Yes. Both CDCF5801ADBQR and CDCF5801DBQR use the 24-SSOP (0.154", 3.90mm Width) package with identical pin configurations, footprints, and mounting requirements for surface mount assembly.

Q: Do both parts support the same input and output signal standards?

A: Yes. Both parts support identical input standards (HSTL, LVPECL, LVTTL) and output standards (HSTL, LVDS, LVPECL, LVTTL, SSTL), enabling direct signal interface compatibility in clock and timing applications.

Q: What are the compliance and environmental ratings for these parts?

A: Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 2 (1 Year) ratings. Both are REACH Unaffected and classified under ECCN EAR99 for export purposes.
