Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout specifications. Cross-reference the datasheet for operating temperature range compliance.

Oscillators Selection Notes

Select this component when a precise 18.003 MHz timing source is required for LVCMOS-compatible logic families. Consider the 1.8V operating voltage constraint and the availability of a power-down feature for battery-sensitive applications. Evaluate the physical size constraints imposed by the 2.0x1.6mm package against available board space.

Oscillators Part Context

This model belongs to the Mercury Electronics SMD oscillator series designed for high-frequency stability. The product line emphasizes miniaturization and low power consumption, catering to modern portable electronics. The 'PD' suffix indicates the inclusion of a power-down control capability within the standard oscillator configuration.

Oscillators Replacement Considerations

Direct substitutes must match the 18.003 MHz frequency, LVCMOS output type, and 1.8V supply voltage. Verify pinout compatibility for the 4-SMD no-lead package. Check if alternative manufacturers offer equivalent thermal and electrical performance characteristics.
