Overview
The DSC8121AI2 is a programmable MEMS oscillator from Microchip Technology, featuring a CMOS output and an enable/disable function. It operates within a supply voltage range of 2.25V to 3.6V and supports frequencies from 10 MHz to 170 MHz with ±25ppm stability. The device is housed in a 6-SMD, no-lead package measuring 7.00mm x 5.00mm x 0.90mm. It has a maximum supply current of 35mA and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Utilizes MEMS technology for robust frequency generation
- Supports programmable frequency configuration via user programming
- Includes hardware enable and disable control functionality
Applications
- General-purpose clocking for digital systems
- Embedded controller timing references
- Communication interface synchronization
Procurement Notes
Verify the specific suffix 'AI2' confirms the -40°C to +85°C industrial temperature rating and 6-SMD package. Ensure ordering documentation specifies the blank/unprogrammed state, as this variant requires end-user programming before operation. Confirm RoHS compliance status matches project requirements.
Selection Notes
Select this component when a programmable MEMS solution is required for space-constrained designs due to its small footprint. Choose over fixed-frequency oscillators if system flexibility allows for post-manufacturing frequency tuning. Ensure the host circuit supports the 2.25V to 3.6V supply range and CMOS logic levels.
Part Context
This part belongs to the DSC8121 series of programmable MEMS oscillators. It shares core architectural features with other variants in the family but differs in temperature grade and package dimensions. The AI2 designation specifically denotes the industrial temperature range and surface-mount packaging suitable for automated assembly processes.
Replacement Considerations
Direct substitutes include other DSC8121 variants with matching package and electrical characteristics, such as DSC8121DI2 or DSC8121CM2, provided they meet the specific temperature and frequency programming requirements.
