Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small 2.0x1.6 mm package size for high-density board designs. Verify that the 27.175 MHz frequency meets the precise timing requirements of the target system without needing external dividers or multipliers.

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 within a consistent 4-SMD no-lead form factor.
