Oscillators Procurement Notes

Verify that the specific part number matches the required frequency, voltage, and output format before ordering. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure compatibility with standard reflow soldering profiles for the specified SMD package dimensions during assembly planning.

Oscillators Selection Notes

Select this component when a stable 146.550 MHz reference is needed within a constrained physical footprint. The LVPECL output is preferred for high-speed digital interfaces requiring low noise. Consider the ±1.0 ppm stability requirement against system timing budgets and verify that the 2.5V supply aligns with existing board power rails.

Oscillators Part Context

This model belongs to the Mercury MQF576P series of QuikXO TCXOs. These oscillators are engineered for flexibility, allowing for customized frequencies with shorter lead times compared to other series. The family supports both 2.5V and 3.3V supplies and offers LVPECL or LVDS outputs, targeting applications where phase jitter and current efficiency are critical design parameters.

Oscillators Replacement Considerations

Direct substitutes may include other MQF576 series variants with different frequencies or voltages, such as MQF576D25-146.550-1.0/-40+85, provided the pinout and electrical characteristics remain compatible. Verify mechanical footprint and thermal requirements before swapping.
