Oscillators Procurement Notes

Verify the specific suffix PD against official documentation to confirm package and lead-free status. Ensure the 1.8V supply requirement aligns with target circuit design. Confirm availability through authorized channels as distribution status may vary. Cross-reference the exact part number to avoid confusion with similar frequency variants within the QHTF series.

Oscillators Selection Notes

Select this component when a 47.3885 MHz reference is required for 1.8V logic systems. Consider the ±50ppm stability specification against system jitter requirements. Evaluate the 4-SMD footprint constraints during PCB layout. Compare thermal performance within the -40°C to 85°C range against environmental conditions.

Oscillators Part Context

This model belongs to the QHTF series of quartz crystal oscillators. The series offers various frequencies and voltage options. The 18 prefix indicates the 1.8V supply variant. The 21 likely denotes package dimensions or pin configuration. The PD suffix typically specifies lead-free compliance and tape/reel packaging.

Oscillators Replacement Considerations

Direct substitutes include other 47.3885 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD no-lead packages. Verify compatibility regarding pinout, height, and stability specifications before substitution.
