Procurement Notes
Verify the specific part number suffix against official Mercury Electronics documentation to confirm the exact frequency tolerance and load capacitance requirements. Ensure that the 1.8V supply voltage aligns with the target system's power rails before procurement. Cross-reference the 4-SMD package dimensions with the mechanical drawing to guarantee compatibility with the PCB footprint.
Selection Notes
Select this oscillator when a precise 75.87 MHz clock source is required for LVCMOS-compatible digital logic. The choice is driven by the need for low-voltage operation at 1.8V and the inclusion of a power-down feature to extend battery life in portable devices. Consider the small form factor of the 4-SMD package for space-constrained board layouts.
Part Context
This component belongs to the Mercury Electronics SMD oscillator series, which specializes in quartz-based frequency control products. The manufacturer has extensive experience in producing crystals, oscillators, and filters. This specific model represents a standard XO variant designed for general-purpose timing applications requiring stable frequency generation.
Replacement Considerations
Consult official Mercury Electronics substitution lists for compatible alternatives. Verify that any substitute matches the 75.87 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions.
