Crystals Procurement Notes

Verify that the specific part number matches the required AEC-Q200 certification level for your application. Confirm the load capacitance requirement of 8 pF aligns with your circuit design specifications. Ensure the operating temperature range of -40°C to +85°C meets your environmental constraints. Check for any specific packaging or reel requirements if applicable to your assembly process.

Crystals Selection Notes

Select this component when a 9 MHz reference is needed for automotive-grade systems. The ±30 ppm stability is suitable for standard communication protocols. Consider the 5x3.2 mm package size against available PCB real estate. Verify compatibility with the target oscillator circuit's capacitive loading requirements before finalizing the design.

Crystals Part Context

This crystal belongs to the AA series from TXC Corporation, which focuses on miniature, high-reliability components. The 'HV' suffix typically denotes specific automotive-grade characteristics within this lineup. It serves as a passive frequency-determining element in active oscillator circuits, providing the precise timing base necessary for digital logic and microcontroller operations in vehicles.

Crystals Replacement Considerations

Direct substitutes must match the 9.000 MHz frequency, 8 pF load capacitance, and AEC-Q200 qualification. Alternative packages may require schematic and layout modifications. Verify that replacement parts maintain the same ±30 ppm stability across the -40°C to +85°C range to ensure system timing integrity.
