Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a stable 30.78 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage if your system architecture relies on low-power logic levels. The compact SMD form factor makes it suitable for space-constrained designs. Evaluate the need for standby capabilities if power efficiency during idle states is a priority for the application.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which offers various frequencies and packaging options. The 'PD' suffix typically indicates specific packaging or tape-and-reel configuration details, though exact definitions should be verified in the official datasheet. Mercury Electronics specializes in quartz crystals and oscillators, providing solutions for diverse timing needs across consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 30.78 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical. Consult the manufacturer's cross-reference list for approved alternatives.
