Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current part number guide to ensure correct packaging and tolerance specifications. Confirm that the requested variant matches the required load capacitance and frequency stability for the target application environment. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

Crystals Selection Notes

Select this component when a standard 38.4 MHz frequency is required for synchronous digital circuits. Ensure the circuit design accommodates the 18 pF load capacitance to maintain frequency accuracy. Verify that the 60 Ohm ESR value is compatible with the oscillator circuit's drive level limitations and start-up requirements.

Crystals Part Context

This component belongs to the 8Z series of quartz crystals from TXC Corporation. The series utilizes seam-seal technology to provide hermetic sealing for the resonator element. This construction method distinguishes it from plastic-packaged alternatives by offering improved reliability against moisture ingress and mechanical stress.

Crystals Replacement Considerations

Potential substitutes include the 8Y-38.400MAHQ-T and 7M-38.400MAHV-T from TXC Corporation. These parts share similar electrical characteristics but may differ in physical dimensions or specific performance tolerances. Verify pinout compatibility and mounting footprint before implementation.
