Substitute Part Grouping Explanation

Substitution of the AX7DBF1-156.2500C is determined by strict equivalence across the following critical parameters:

• Frequency: 156.25 MHz (exact match required)
• Output Type: LVDS (electrical interface specification)
• Supply Voltage: 2.5V (power requirement)
• Function: Enable/Disable (control capability)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (physical and electrical interface)
• Package Dimensions: 7.00mm x 5.00mm (footprint compatibility)

The AX7DBF3-156.2500C meets all these criteria and is classified as a parametric equivalent substitute.
