Oscillators Procurement Notes

Verify the specific datasheet for the 18QHTF21-38.395-PD to confirm exact electrical parameters such as jitter, stability, and load capacitance requirements. Ensure that the 1.8V supply voltage aligns with your system design before procurement. Check for any specific handling instructions related to the no-lead SMD package.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 38.395 MHz reference. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small 2.0x1.6 mm footprint if board space is limited. Verify that the operating temperature range meets your environmental specifications.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD no-lead form factor. The series typically provides LVCMOS outputs and supports power-down modes. Similar parts in the series include different frequency variants like 6.000 MHz or 96.768 MHz, maintaining consistent package and voltage characteristics.

Oscillators Replacement Considerations

Direct substitutes must match the 38.395 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal performance. Cross-reference with other manufacturers offering similar MEMS or quartz oscillators in the same footprint.
