DSC8122CI2T

Overview

The DSC8122CI2T is a programmable MEMS oscillator manufactured by Microchip Technology, housed in a compact 6-SMD, no-lead package. It supports an available frequency range from 10 MHz to 460 MHz with LVPECL output configuration. The device operates on a supply voltage of 2.25V to 3.6V and features enable/disable functionality. It exhibits a frequency stability of ±25ppm over the operating temperature range of -40°C to +85°C. The maximum supply current is 58mA, and it meets AEC-Q100 automotive qualification standards.

Feature Summary

• Utilizes MEMS technology for robust clock generation within a small surface-mount footprint.
• Offers wide programmability across a broad frequency spectrum from 10 MHz to 460 MHz.
• Provides LVPECL output interface suitable for high-speed digital applications.
• Includes hardware enable and disable control capabilities for power management.

Applications

• Automotive infotainment systems requiring AEC-Q100 qualified components
• High-speed data communication interfaces utilizing LVPECL signaling
• Industrial equipment needing stable programmable clock sources

Procurement Notes

Verify that the specific part number matches the required frequency and package variant, as the DSC8122 series includes multiple configurations. Confirm that the 'Blank' programming status aligns with your design workflow, as user programming is mandatory before deployment. Ensure compatibility with the 2.25V to 3.6V supply rails and LVPECL load requirements. Check for any recent PCN updates regarding marking or packaging changes to ensure supply chain continuity.

Selection Notes

Select this component when a programmable MEMS oscillator with LVPECL outputs is required for automotive or industrial environments. It is suitable for designs needing flexibility in frequency selection between 10 MHz and 460 MHz. Consider the ±25ppm stability and -40°C to +85°C temperature range against system specifications. Evaluate the 6-SMD package size constraints and 58mA current consumption against board space and power budget limitations.

Part Context

This component belongs to the DSC8122 family of programmable MEMS oscillators from Microchip Technology. The family shares common architectural features but varies in output types, frequencies, and packages. The DSC8122CI2T specifically denotes the LVPECL output variant in the 6-SMD package. It complements other series like DSC11x3 for different performance or interface needs.
