Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under your environmental conditions.

Selection Notes

Select this component when a stable 86.105 MHz reference is required with low-voltage operation. Consider the enable pin feature if power conservation during idle states is necessary. Evaluate the LVCMOS output swing against your receiving logic levels. Compare package dimensions against available board space to ensure mechanical fit within the assembly.

Part Context

This oscillator belongs to the Mercury Electronics series of quartz-based frequency control products. The manufacturer specializes in various crystal and oscillator types, including TCXO and VCXO variants.
