Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under your intended environmental conditions.

Selection Notes

Select this component when a precise 7.3723 MHz clock source is required for low-voltage digital systems. The LVCMOS output ensures compatibility with standard logic families. Consider the power-down feature if energy efficiency during idle states is a priority. Verify that the 1.8V operating voltage meets the target application's power budget and signal integrity requirements.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The 'PD' suffix indicates the inclusion of a power-down control pin. Mercury Electronics specializes in quartz-based timing components, providing reliable frequency control solutions for consumer and industrial electronics.

Replacement Considerations

Direct replacements must match the 7.3723 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check datasheets for compatible parts from other manufacturers offering identical electrical characteristics and pinout configurations to ensure seamless integration without redesigning the PCB.
