• Data communication interfaces requiring precise clock sources

Oscillators 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 PCB footprint matches the 2.0x1.6mm SMD package dimensions. Check for any specific reflow soldering profile recommendations from the manufacturer datasheet to ensure reliability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The small 2.0x1.6mm footprint makes it suitable for dense PCB layouts. Consider the enable/disable feature if power efficiency is a priority. Verify that the operating temperature range meets your environmental specifications. Compare against other Mercury oscillators in the 18QHTF series for alternative frequencies or package sizes.

Oscillators Part Context

This part belongs to the 18QHTF series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies with LVCMOS outputs and low-voltage support. Similar parts include the 18QHTF21-65.300-OE and 18QHTF21-37.888-OE, which share the same package and electrical characteristics but differ in nominal frequency. The 'OE' suffix likely indicates a specific packaging or tape-and-reel configuration.

Oscillators Replacement Considerations

Direct replacements must match the 41.65714 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Other Mercury parts like 18QHTF21-4.31818-OE are not compatible due to frequency differences. Cross-brand replacements require careful verification of pinout, voltage levels, and timing parameters.
