Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX5PBF3-1000.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1 GHz (exact match required)
• Output Type: LVPECL (signal integrity dependent)
• Supply Voltage: 2.5V (circuit compatibility)
• Function: Enable/Disable capability (operational requirement)
• Frequency Stability: ±20ppm (timing accuracy)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (PCB layout compatibility)
• Package Dimensions: 5.00mm x 3.20mm x 1.50mm maximum height (physical fit)
• Supply Current Specifications: 110mA maximum, 100mA disable mode (power budget)
• Compliance: ROHS3 Compliant, MSL 1 (regulatory and handling requirements)

The AX5PBF1-1000.0000C meets all these criteria and is classified as a parametric equivalent.
