SXT2248ED17-48.000M

Crystals Overview

The SXT2248ED17-48.000M is a 48.000 MHz AT-cut fundamental mode crystal oscillator manufactured by Suntsu Electronics, Inc. It features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 50 Ohms. The component is housed in a 4-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm. It operates within a temperature range of -10°C to +70°C and offers frequency stability options of ±15 ppm or ±20 ppm.

Crystals Feature Summary

• Four-pad surface-mount design provides enhanced electromagnetic interference shielding compared to two-pin variants.
• AT-cut fundamental resonance ensures simple oscillation circuit requirements without additional matching inductors.
• Industrial-grade thermal stability supports reliable operation across specified temperature ranges.

Crystals Applications

• Bluetooth low energy (BLE) communication modules
• Short-range wireless devices such as Zigbee transceivers
• PCMCIA cards and modem interfaces
• High-density industrial control systems

Crystals Procurement Notes

Verify the specific frequency tolerance variant required for your application, as datasheets indicate availability in both ±15 ppm and ±20 ppm configurations. Confirm that the operating temperature range of -10°C to +70°C aligns with your environmental constraints. Ensure the 4-SMD footprint matches your PCB layout guidelines. Request the official SXT224 Series datasheet for precise electrical testing conditions and aging rate specifications before finalizing orders.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but electromagnetic compatibility demands exceed standard two-pin crystal capabilities. The four-pad structure facilitates direct grounding for improved noise immunity in RF circuits. Choose based on the necessary frequency stability; ±15 ppm suits stricter synchronization needs, while ±20 ppm may offer cost benefits for less critical timing applications. Verify the 50 Ohm ESR limit fits your oscillator circuit's drive level requirements.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series utilizes a 4-pad configuration designed to mitigate electromagnetic interference in compact wireless designs. Unlike higher-frequency overtone modes, this 48 MHz unit employs fundamental AT-cut technology, simplifying circuit design. The series covers various frequencies between 12 MHz and 66 MHz with different load capacitance options.

Crystals Replacement Considerations

Direct substitutes must match the 2520-4P package, 48 MHz frequency, 8 pF load capacitance, and ≤50 Ohm ESR. Verify that alternative components support the same -10°C to +70°C operating range. Cross-reference pinout definitions to ensure the ground shield pins align correctly with your PCB layout to maintain EMC performance.
