Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration matches your production requirements. Confirm that the thermal characteristics align with your system's environmental constraints. Cross-reference the datasheet parameters against your circuit design specifications to guarantee compatibility with your oscillator circuitry. Ensure compliance with relevant material regulations for your target market.

Crystals Selection Notes

Select this component when a 20MHz fundamental crystal is required in a small footprint. Consider the ±10ppm stability requirement against your system's jitter tolerance. Evaluate the -20°C to +70°C temperature range against your application's operating conditions. Compare the 60 Ohm ESR with your oscillator circuit's drive level limitations to prevent overdriving the crystal.

Crystals Part Context

This part belongs to TXC Corporation's line of miniature surface-mount crystals. The 7M series typically offers low-profile packages suitable for space-constrained designs.
