Crystals Procurement Notes

Verify the specific ordering suffix S999-542 against the manufacturer's official datasheet to confirm the exact electrical parameters, including the 38.4 MHz frequency and 8pF load capacitance. Ensure the package type matches the required 4-SMD no-lead form factor for PCB layout compatibility. Cross-reference the RoHS compliance status if environmental regulations apply to your manufacturing process.

Crystals Selection Notes

Select this component when a small form factor is critical alongside moderate frequency stability requirements. The 80 Ohm ESR value should be compatible with the host oscillator circuit's drive level specifications. Consider the operating temperature range defined in the datasheet to ensure performance consistency across the intended application environment.
