Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 37.632 MHz specification before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the PCB footprint accommodates the 2.0x1.6mm SMD package dimensions. Check for any specific reflow soldering profile requirements provided in the manufacturer datasheet to ensure joint integrity.

Oscillators Selection Notes

Select this component when a precise 37.632 MHz clock source is required for LVCMOS-compatible circuits. The choice depends on the availability of a 1.8V supply rail within the design. Consider the physical space constraints as the package size is limited to 2.0x1.6mm. Evaluate if the enable/disable functionality is necessary for meeting system power efficiency targets compared to always-on oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronic. The series typically offers various frequencies and voltage options within small form factors. These components are generally used where stable timing references are critical for synchronous data transfer and processor operation in portable or space-constrained electronic devices.

Oscillators Replacement Considerations

Direct substitutes must match the 37.632 MHz frequency, 1.8V operating voltage, LVCMOS output type, and 4-SMD 2.0x1.6mm package. Verify that alternative manufacturers provide equivalent electrical characteristics and thermal performance. Ensure the replacement part supports the same enable/disable control logic if that feature is utilized in the design.
