Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check the datasheet for the recommended soldering profile to maintain component integrity during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS outputs. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor if space is limited on the PCB. Verify that the 31.104 MHz frequency meets the exact timing needs of the target application without additional dividers.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which focuses on quartz-based timing solutions. The manufacturer has extensive experience in producing crystals and oscillators since 1973. This specific model represents their standard XO line, offering reliable performance for general electronic applications requiring stable clock signals.

Oscillators Replacement Considerations

Direct substitutes must match the 31.104 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before substitution. Consult the manufacturer's cross-reference list for approved alternatives.
