DSC8121DI5

Overview

The DSC8121DI5 is a programmable MEMS oscillator manufactured by Microchip Technology, operating within a frequency range of 10 MHz to 170 MHz. It utilizes CMOS output logic and supports a supply voltage between 2.25 V and 3.6 V. The device features an enable/disable function and offers a total frequency stability of ±10 ppm. Designed for surface mount installation, it is housed in a compact 4-lead QFN package measuring 3.2 mm by 2.5 mm with a maximum height of 0.90 mm. The component operates reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes MEMS technology for enhanced reliability and shock resistance compared to traditional quartz oscillators.
• Features a programmable architecture allowing users to configure specific frequencies within the supported range.
• Includes an enable/disable control pin to manage power consumption during inactive periods.

Applications

• High-speed data communication interfaces requiring precise clock synchronization
• Embedded systems and microcontroller boards needing stable timing references
• Industrial equipment requiring robust performance under varying environmental conditions

Procurement Notes

Verify the exact suffix against official Microchip documentation to ensure correct package type and temperature rating. Confirm that the blank programming state matches system requirements before integration. Check for recent Product Change Notifications regarding marking or packaging updates. Ensure compatibility with RoHS3 and REACH regulations for target markets. Validate lead times as manufacturing schedules may vary based on current demand.

Selection Notes

Select this model when a small footprint and high frequency stability are critical. The 4-lead QFN package suits space-constrained designs. Consider the ±10 ppm stability requirement against other series options like the DI2 variant if tighter tolerance is needed. Evaluate the 2.25V to 3.6V supply range against system power rails. Verify that the programmable nature fits the production workflow for frequency customization.

Part Context

This component belongs to the DSC8121 series of programmable MEMS oscillators from Microchip Technology. The series offers various package options and stability grades to suit different design needs. The DI5 suffix specifically denotes the 4-lead QFN package and ±10 ppm stability grade within this family.

Replacement Considerations

DSC8121DI2 is a direct substitute offering identical electrical specifications but with ±25 ppm stability instead of ±10 ppm. Both share the same 4-lead QFN package and operational parameters. Verify that the stability difference meets application requirements before swapping.
