Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct tolerance and packaging specifications. Confirm that the requested part matches the exact frequency and load capacitance requirements of the target design. Cross-reference the datasheet for any recent updates regarding pin configuration or recommended soldering profiles to guarantee compatibility with current manufacturing processes.

Crystals Selection Notes

Select this component when a standard 6.7888 MHz reference signal is required for systems utilizing 20 pF load capacitors. Consider the physical dimensions and surface-mount form factor for PCB layout constraints. Evaluate the ESR value of 80 Ohms against the oscillator circuit's drive level limitations to prevent over-driving the crystal element during operation.

Crystals Part Context

This model belongs to the broader category of passive frequency control components produced by TXC Corporation. It serves as a fundamental resonator element within larger electronic assemblies, providing the stable oscillation necessary for digital logic synchronization. Unlike active oscillators, this device requires an external circuit to generate the output signal, functioning primarily as a precision frequency-determining element.

Crystals Replacement Considerations

Direct substitutes must match the 6.7888 MHz frequency, 20 pF load capacitance, and 80 Ohm ESR specifications. Verify that alternative manufacturers offer identical SMD package dimensions to ensure mechanical fit without redesigning the PCB footprint.
