Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connection.

Oscillators Selection Notes

Select this component when a 38.4 MHz clock source is required with low-voltage operation. Consider the LVCMOS output level compatibility with downstream logic families. Evaluate the physical dimensions of the 4-SMD package against available board space constraints. Verify thermal performance within the specified operating temperature range for the intended application environment.

Oscillators Part Context

This model belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies including 8.4 MHz, 44.2 MHz, and 96.768 MHz variants. All units share similar packaging and voltage characteristics, differing primarily in their nominal operating frequencies and specific timing parameters defined in their respective datasheets.

Oscillators Replacement Considerations

Direct substitutes include other 38.4 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications such as jitter and phase noise before substitution. Cross-reference with Mercury Electronics part numbers like 18QHTF21-38.400 without the OE suffix if applicable.
