Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZL40225LDG1 is determined by strict equivalence across the following critical parameters:

• Functional Type: Fanout Buffer (Distribution), Multiplexer with identical 2:8 input-to-output ratio
• Frequency Capability: Maximum operating frequency of 750 MHz
• Signal Compatibility: Support for differential input (CML, HCSL, LVCMOS, LVDS, LVPECL) and LVPECL output
• Electrical Specifications: Supply voltage range 2.375V ~ 3.465V and operating temperature range -40°C ~ 85°C
• Package Compatibility: 32-VFQFN Exposed Pad (32-QFN 5x5) surface mount package
• Compliance Standards: ROHS3 compliance, REACH unaffected status, and MSL 3 rating

The ZL40224LDG1 meets all these criteria and is classified as a parametric equivalent.
