Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and output types. Confirm that the 4-SMD No Lead package dimensions match the target PCB footprint. Check datasheet specifications for operating temperature ranges and load capacitance requirements before integration into final designs.

Oscillators Selection Notes

Select this component when a fixed frequency of 75.635 MHz is required with LVCMOS compatibility. Consider the 3.3V supply constraint and the need for power-down capabilities. Evaluate the small form factor against available board space. Ensure the application does not require differential outputs or spread spectrum features.

Oscillators Part Context

This part belongs to the 3QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and packaging options. The PD suffix typically indicates a specific tape and reel packaging format or variant within the manufacturer's lineup, distinct from other suffixes like OE.

Oscillators Replacement Considerations

Direct substitutes include other 75.635 MHz LVCMOS oscillators in 4-SMD packages. Verify pinout compatibility and electrical parameters such as current consumption and startup time. Cross-reference with Mercury Electronics' own variants if different packaging is needed.
