Oscillators Procurement Notes

Verify the specific output logic level and load capacitance requirements against the target circuit design before procurement. Confirm that the 2.5V supply rail meets the current consumption specifications during peak operation. Ensure the PCB layout adheres to the recommended footprint dimensions to maintain signal integrity and thermal performance.

Oscillators Selection Notes

Select this model when a precise 66.666667 MHz reference is required with low power consumption. Consider the LVDS output for noise immunity in high-density designs. Evaluate the -40°C to +85°C operating range against environmental constraints. Compare phase noise specifications with alternative oscillators if strict jitter budgets apply to the system clock.

Oscillators Part Context

This part belongs to the QMQF326D25 series of miniature TCXOs from Mercury Electronics. The series offers various frequencies and output types within a standard 6-pin SMD form factor. These components are engineered to replace larger through-hole crystals or standard XO modules in modern portable and industrial electronics requiring precise timing.

Oscillators Replacement Considerations

Direct substitutes include other 66.666667 MHz LVDS TCXOs in 6-SMD packages from manufacturers such as IQD or SiTime. Verify pin compatibility and electrical parameters before substitution. Generic family replacements may require firmware adjustments if output drive strengths differ.
