Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDCF5801DBQ are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be equivalent for a part to serve as a direct substitute:

• Maximum frequency: 280MHz
• Supply voltage range: 3V ~ 3.6V
• Input signal levels: HSTL, LVPECL, LVTTL
• Output signal levels: HSTL, LVDS, LVPECL, LVTTL, SSTL
• Package type: 24-SSOP (0.154", 3.90mm Width)
• Operating temperature range: -40°C ~ 85°C
• Functional type: PLL Multiplier/Divider with 1:1 input-to-output ratio
• Differential input/output capability: No/Yes

The CDCF5801ADBQ meets all these criteria and is classified as a direct manufacturer substitute.

Parameter Comparison

Engineering Selection Recommendations

The CDCF5801ADBQ is the direct substitute for the CDCF5801DBQ. Both components share identical electrical specifications, package dimensions, and functional characteristics. The primary distinction is product status: the CDCF5801DBQ is classified as "Not For New Designs," while the CDCF5801ADBQ maintains active status. For applications requiring continued component availability and long-term supply assurance, the CDCF5801ADBQ is the appropriate selection. Both parts comply with ROHS3 and maintain equivalent export classification (EAR99) and tariff codes (HTSUS 8542.39.0001).
