Crystals Procurement Notes

Verify that the specific part number matches the required automotive grade specifications, particularly the AEC-Q200 certification status. Confirm the seam seal package type is suitable for the intended environmental conditions. Ensure the load capacitance and ESR values align with the target oscillator circuit design parameters before finalizing procurement decisions.

Crystals Selection Notes

Select this component when designing circuits requiring high-frequency stability in extreme temperature ranges typical of automotive environments. The 48 MHz frequency is suitable for clock generation in digital processing units. Consider the small form factor for space-constrained PCB layouts. Verify compatibility with the host system's load capacitance requirements to ensure accurate frequency performance.

Crystals Part Context

This part belongs to TXC Corporation's automotive-grade crystal lineup, specifically utilizing seam seal technology for enhanced durability. It is distinct from standard commercial crystals due to its rigorous qualification testing and wider operating temperature range. The 48 MHz output serves as a precise timing reference for synchronous data transmission and processing tasks within vehicle networks.
