Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 2.5V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to prevent soldering defects.

Oscillators Selection Notes

Select this component when a precise 67.728 MHz reference is required with low-power standby capabilities. Consider the LVCMOS output swing limits relative to the receiving input thresholds. Evaluate the thermal performance within the operating temperature range to ensure long-term frequency stability under varying environmental conditions.

Oscillators Part Context

This oscillator belongs to the 25QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products.
