• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Confirm that the 1.8V supply requirement aligns with the target system design. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connectivity.

Selection Notes

Select this component when a precise 7.3728 MHz clock source is required for LVCMOS-compatible circuits. Consider the 1.8V supply constraint and the need for enable/disable control features. Evaluate the small 2.0x1.6 mm package size against available board space constraints and thermal management requirements for the specific application environment.

Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized 4-SMD no-lead form factor. These components are designed for applications requiring stable clock signals in space-constrained electronic devices.

Replacement Considerations

Compatible substitutes include other 18QHTF21 series variants with identical pinout and package dimensions but different frequencies, such as 18QHTF21-37.888-OE or 18QHTF21-13.1313-OE, provided the frequency difference is acceptable for the application.
