SXT2248AA07-24.576M

Crystals Overview

The SXT2248AA07-24.576M is a ceramic surface-mount crystal from Suntsu Electronics, Inc., housed in a compact 2.5mm x 2.0mm 4-pad package. It operates at a fundamental frequency of 24.576 MHz with an AT-cut design. The component features a load capacitance of 8 pF and a maximum equivalent series resistance (ESR) of 80 Ω within the 20–30 MHz range. Frequency tolerance and stability are rated at ±50 ppm across the commercial temperature range of 0°C to +70°C. The device supports a maximum drive level of 100 μW and includes four solder pads for enhanced grounding and electromagnetic interference shielding.

Crystals Feature Summary

• Four-pad ceramic SMD construction provides superior grounding and EMI shielding compared to standard two-pin designs.
• AT-cut fundamental resonance ensures simple oscillator circuit requirements without additional matching inductors.
• Compact 2.5mm x 2.0mm footprint enables high-density layout for space-constrained wireless applications.

Crystals Applications

• Bluetooth Low Energy (BLE) modules
• Short-range wireless communication devices
• Industrial control systems with dense PCB layouts

Crystals Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact electrical tolerances and temperature ranges. Ensure the ordering information matches the required load capacitance and stability specifications for the target application. Confirm RoHS compliance status through manufacturer documentation prior to procurement.

Crystals Selection Notes

Select this component when a small form factor is critical for RF performance. The four-pad design offers better noise immunity than two-pin alternatives. Verify that the system oscillator circuit can support the specified 80 Ω ESR limit. Ensure the operating environment remains within the 0°C to +70°C range defined by the AA07 suffix.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic crystals. The series utilizes a 4-pad configuration to improve signal integrity in high-frequency applications. It serves as a timing reference for microcontrollers and RF transceivers requiring precise clock signals in consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other 2520 4-pad crystals with identical 24.576 MHz frequency, 8 pF load capacitance, and compatible ESR limits. Cross-reference pinout compatibility and thermal characteristics before substitution.
