Crystals Procurement Notes

Verify the specific suffix 'I' against official manufacturer documentation to confirm pin configuration and tape/reel specifications. Ensure compatibility with PCB footprints matching the 3.2x2.5mm dimensions. Cross-reference RoHS compliance status directly with the latest datasheet revision before integration into production designs.

Crystals Selection Notes

Select this component when a 48 MHz reference with ±10 ppm accuracy is required within a -20°C to +70°C environment. Compare ESR values against oscillator circuit requirements to ensure reliable startup. Consider the 10pF load capacitance requirement for proper circuit tuning and frequency accuracy.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation. The series offers various frequency options in standard SMD packages. The 7M series is characterized by low profile designs suitable for space-constrained electronic assemblies requiring stable oscillation frequencies.

Crystals Replacement Considerations

Direct substitutes may include other 48 MHz crystals with identical 3.2x2.5mm dimensions, 10pF load capacitance, and ±10 ppm tolerance. Verify that alternative parts match the 50 Ohm ESR specification and support the same operating temperature range.
