Procurement Notes
Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before procurement. Ensure the operating temperature range meets your environmental specifications. Confirm that the LVCMOS output voltage levels are compatible with the receiving logic inputs of your target application to prevent signal integrity issues.
Selection Notes
Select this component when a low-voltage, single-ended LVCMOS clock source is required. Consider the enable pin utility for power-sensitive designs. Evaluate the package dimensions for PCB layout constraints. Compare performance against other Mercury oscillators if different frequencies or output types are needed.
Part Context
This part belongs to Mercury's series of quartz crystal oscillators. Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency control products including crystals, filters, and oscillators. The company has decades of experience in the quartz industry, providing timing solutions for various electronic applications globally.
Replacement Considerations
Direct substitutes may include other 7.6 MHz LVCMOS oscillators from Mercury with identical pinouts and electrical characteristics. Verify compatibility with alternative manufacturers' parts by matching supply voltage, output type, and physical dimensions. Cross-reference datasheets for equivalent performance metrics.
