DSC8121CI2T

Overview

The DSC8121CI2T is a programmable MEMS oscillator from the DSC8121 series, manufactured by Microchip Technology. It operates within a frequency range of 10 MHz to 170 MHz and features a CMOS output format. The device supports a supply voltage between 2.25 V and 3.6 V, with a maximum supply current of 35 mA. It offers a frequency stability of 25 ppm and functions across an operating temperature range of -40°C to +85°C. The component is housed in a compact 6-SMD, no-lead package, suitable for surface mount applications.

Feature Summary

• Utilizes MEMS technology for reliable oscillation
• Programmable blank configuration requiring user enablement
• Supports enable/disable functionality for power management

Applications

• General clock generation in embedded systems
• Data communication interfaces requiring stable timing
• Consumer electronics with space-constrained designs

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm that the part is listed as 'Unprog' or blank, meaning it requires external programming for frequency configuration. Ensure compatibility with the required voltage levels and temperature range for the target application environment before finalizing procurement.

Selection Notes

Select this model when a small footprint and low power consumption are critical. The CMOS output is suitable for direct interfacing with digital logic. Consider the 25 ppm stability requirement against system jitter specifications. Verify that the programmable nature aligns with the production workflow, as these parts are not pre-configured at the factory.

Part Context

This component belongs to the DSC8121 family of programmable MEMS oscillators. It shares architectural similarities with other variants in the series but differs in package type and operational parameters. The CI2T designation specifically denotes the tape and reel packaging option, facilitating automated assembly processes compared to tube-packaged equivalents.

Replacement Considerations

Direct substitutes include other DSC8121 variants with compatible packages and electrical specifications, such as DSC8121CI2. Cross-referencing pinout configurations and voltage tolerances is essential when considering alternative sources or upgraded models within the same product line.
