Substitute Part Grouping Explanation

Substitution of the 9DB801CFLF is determined by strict equivalence across the following critical parameters:

• Package / Case: 48-BSSOP (0.295", 7.50mm Width) — physical and electrical compatibility
• Mounting Type: Surface Mount — PCB assembly compatibility
• Frequency - Max: 400MHz — operational bandwidth requirement
• Ratio - Input:Output: 1:8 — functional distribution capability
• Differential - Input:Output: Yes/Yes — signal integrity requirement
• Voltage - Supply: 3.135V ~ 3.465V — power supply compatibility
• Operating Temperature: 0°C ~ 70°C — thermal operating range
• Input Type: HCSL — signal standard compatibility
• Output Type: HCSL or LVDS — output signal standard compatibility
• Number of Circuits: 1 — functional architecture

The 9DB803DFLF meets all substitution criteria and is classified as an active product, providing long-term availability and support.
