Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Confirm that the 1.8V supply voltage requirement aligns with the target system design. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 4-SMD form factor for space-constrained boards. Validate that the 14.285 MHz frequency meets the system's timing requirements without additional dividers.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The suffix -OE typically denotes specific packaging or ordering configurations. These oscillators are part of Mercury's broader portfolio of quartz-based frequency control products, including TCXOs and VCXOs.

Oscillators Replacement Considerations

Direct replacements must match the 14.285 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as load current and duty cycle. Consult manufacturer cross-reference lists for verified equivalents.
