Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliable assembly and long-term performance stability.

Oscillators Selection Notes

Select this component when a low-frequency, low-voltage oscillator with enable functionality is required. The 2.176 MHz frequency is suitable for baud rate generation or specific clock division needs. Consider the small form factor if board space is limited. Verify that the LVCMOS output swing is compatible with the input thresholds of the downstream logic devices in your application circuit.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes the presence of an Output Enable pin. These oscillators are designed for general-purpose timing applications where size and power consumption are critical factors.
