Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DBF2-148.5000C is determined by strict equivalence across the following critical parameters:

• Frequency: 148.5 MHz (exact match required)
• Output Type: LVDS (signal integrity dependent)
• Supply Voltage: 2.5V (circuit compatibility required)
• Function: Enable/Disable capability (system control requirement)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (PCB layout compatibility)
• Package Dimensions: 7.00mm x 5.00mm (footprint requirement)

The AX7DBF3-148.5000C meets all these parameters identically, establishing it as a parametric equivalent within the ClearClock™ AX7 series.

Parameter Comparison
