Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint oscillator with control pins is required. Consider the operating temperature range and stability requirements relative to the application environment. Evaluate the need for enable/disable features versus always-on operation to optimize system power consumption effectively.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal oscillators. The manufacturer has decades of experience in Taiwan producing frequency control products including TCXOs and VCTCXOs. This series represents their standard XO offerings designed for modern electronic devices requiring precise timing.

Oscillators Replacement Considerations

Direct substitutes must match the 28.2153 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify equivalent electrical characteristics such as phase noise and jitter if available in official documentation.
