Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for your application environment.

Oscillators Selection Notes

Select this component when a stable 3.2496 MHz reference is required for low-power systems. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the 1.8V supply constraint and standby feature for energy-efficient designs. Verify that the small form factor fits within the available board space constraints for the target assembly.

Oscillators Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency-control products, including quartz crystals and oscillators. The company has a history dating back to 1973, focusing on precision timing components. This part belongs to their series of surface-mount crystal oscillators designed for modern electronic applications requiring reliable clock signals.

Oscillators Replacement Considerations

Direct substitutes must match the 3.2496 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications such as current consumption and startup time. Cross-reference with other manufacturers offering equivalent XO specifications if Mercury parts are unavailable.
