Procurement Notes
Verify the exact frequency tolerance and load capacitance requirements against the specific application datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official mechanical drawing to prevent assembly issues.
Selection Notes
Select this component when a low-voltage, surface-mount oscillator with enable functionality is required. The 7.3278 MHz frequency suits specific baud rate or clock division needs. Consider the 1.8V operating range if the design prioritizes low power consumption over higher drive capabilities found in 3.3V variants.
Part Context
Mercury Electronic Ind. Co., Ltd. is a manufacturer with decades of experience in quartz crystals and frequency control products. This model belongs to their series of standard XO oscillators, which are designed for reliable use in various electronic applications. The company emphasizes precision manufacturing and long-term stability in its frequency control solutions.
Replacement Considerations
Direct substitutes include other 7.3278 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify electrical parameters such as supply voltage, current consumption, and output swing. Mechanical compatibility requires matching the 4-SMD no-lead footprint and pin configuration.
