Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant are selected. Confirm that the 1.8V supply voltage aligns with the target circuit design requirements. Ensure the LVCMOS output level matches the receiving component's input specifications. Check the operating temperature range against environmental conditions. Validate the enable/disable pin configuration for proper integration.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. Consider the small 4-SMD footprint for space-constrained designs. Evaluate the need for active enable/disable control to manage power consumption. Compare the 66.562 MHz frequency against other available options if different timing is needed. Ensure LVCMOS compatibility with downstream logic gates.

Part Context

This part belongs to the Mercury Electronics standard XO series, which provides reliable clock signals for various electronic devices. The manufacturer specializes in quartz crystals and oscillators, offering a range of frequencies and packages. This specific model represents a standard output type within their portfolio, designed for general-purpose digital applications requiring stable frequency generation.

Replacement Considerations

Direct substitutes may include other 66.562 MHz LVCMOS oscillators from Mercury or compatible manufacturers with matching 1.8V supply and 4-SMD package dimensions. Verify electrical parameters such as load capacitance and drive strength before substitution. Ensure the replacement supports the same enable/disable functionality if required by the design.
