- LVCMOS output logic for digital interface compatibility
- Integrated enable and disable control functionality
- Compact surface-mount package design
Applications
- General purpose clock signal generation
- Digital system timing references
- Embedded electronics applications
Procurement Notes
Verify the specific suffix 'OE' against official Mercury Electronic documentation to confirm the enable/disable pin configuration. Ensure the 1.8V supply requirement aligns with target circuit designs. Confirm package dimensions match PCB footprint constraints before integration.
Selection Notes
Select this model when a 75.475 MHz LVCMOS clock source is required with low voltage operation. Consider the 2.0x1.6mm form factor for space-constrained layouts. Validate that the enable/disable feature meets system power management requirements.
Part Context
This part belongs to the Mercury Electronic XO series, which manufactures quartz crystals and oscillators. The company has a history dating back to 1973 in Taiwan, specializing in frequency control products including TCXO and VCXO variants.
Replacement Considerations
Cross-reference with other 75.475 MHz LVCMOS oscillators in the same package size. Verify electrical parameters such as supply voltage and output swing compatibility before substitution.
