DSC8121AM2

Overview

The DSC8121AM2 is a programmable MEMS oscillator from Microchip Technology, housed in a VDFN-6 package. It operates on a supply voltage of 2.25V to 3.6V with a maximum supply current of 35mA and a disabled current of 22mA. The device supports output frequencies from 10 MHz to 170 MHz with CMOS output format. It features a frequency stability of ±25ppm and functions within an extended industrial temperature range of -55°C to +125°C. The component utilizes DSPLL technology for low jitter performance.

Feature Summary

• Built-in programmability allows users to configure specific clock frequencies without external components.
• MEMS-based architecture provides robust resistance to shock and vibration compared to traditional quartz crystals.
• Extended temperature rating ensures reliable operation in harsh industrial environments up to 125°C.
• Integrated enable/disable functionality supports power management strategies in battery-operated systems.

Applications

• Industrial automation control systems requiring precise timing under extreme temperatures
• Telecommunications infrastructure equipment needing stable clock sources
• Medical imaging devices demanding low-jitter signal generation
• Automotive electronics operating in high-vibration environments

Procurement Notes

Verify the suffix AM2 confirms the -55°C to +125C temperature range and VDFN-6 package before ordering. Ensure the blank programming state matches your design requirements, as user programming is mandatory. Confirm RoHS compliance status via the latest datasheet revision. Check lead times as production cycles may vary based on factory schedules.

Selection Notes

Select this model when extended temperature capability beyond standard industrial ranges is required. Compare against AI2 variants if lower cost or different packaging suits the application better. Consider the 10MHz to 170MHz frequency span to ensure coverage of target clock speeds. Evaluate power consumption constraints given the 35mA max supply current during active operation.

Part Context

Part of the DSC8121 series of programmable MEMS oscillators designed by Microchip Technology. This series replaces discrete crystal resonators and buffer ICs, reducing board space and assembly complexity. The DSC8121AM2 specifically targets applications requiring wide temperature tolerance and high reliability in compact form factors.

Replacement Considerations

DSC8121AI2 offers similar electrical characteristics but with a narrower -40°C to +85°C temperature range and QFN-4 package. DSC8121AL2 provides a wider frequency range up to 170MHz but lacks the extended temperature rating. Verify pin compatibility and thermal requirements when substituting.
