DSC8103AI2T

Overview

The DSC8103AI2T is a programmable MEMS oscillator from Microchip Technology, designed for high-performance applications requiring low jitter. It operates within a supply voltage range of 2.25V to 3.6V and supports frequencies up to 170 MHz with a stability of 25 PPM. The device features LVCMOS output format and is housed in a compact 7mm x 5mm x 0.85mm surface-mount package. It functions reliably across an industrial temperature range of -40°C to +85°C, drawing a maximum current of 6 mA.

Feature Summary

• Utilizes silicon MEMS technology for superior vibration resistance compared to traditional quartz crystals.
• Field-programmable architecture allows for flexible frequency customization during manufacturing or deployment.
• Delivers low jitter performance suitable for sensitive digital communication interfaces.

Applications

• RS-232 extended distance applications
• RS-422 communication systems
• Computer communications

Procurement Notes

Verify the specific frequency configuration required for your design, as this component is supplied as a blank unprogrammed unit. Confirm that your programming equipment is compatible with Microchip's field-programmable specifications before procurement. Ensure the selected package size matches your PCB footprint requirements.

Selection Notes

Select this model when low jitter and robustness against mechanical shock are critical. Consider the need for post-manufacturing frequency tuning capabilities. Evaluate the power consumption constraints against the 6 mA typical draw. Verify compatibility with the target system's voltage levels and interface standards.

Part Context

This part belongs to the DSC8103 series of precision oscillators. It represents a shift towards MEMS-based timing solutions that offer better reliability and programmability than fixed-frequency crystal oscillators. The AI2T suffix indicates the specific package type and tape-and-reel packaging for automated assembly.

Replacement Considerations

Direct replacements may include other models from the DSC8103 family with different frequency options or output formats. Cross-reference pinout and electrical characteristics carefully when substituting with generic MEMS oscillators from other manufacturers.
