DSC8124CI5

Overview

The DSC8124CI5 is a programmable MEMS oscillator manufactured by Microchip Technology. It operates within a frequency range of 10 MHz to 460 MHz and supports HCSL output logic. The device functions on a supply voltage of 2.25V to 3.6V, with a maximum supply current of 42mA. It features enable/disable functionality and offers frequency stability options including ±10ppm and ±25ppm variants. The component is housed in a 6-VDFN package measuring 5.00mm x 3.20mm x 0.90mm. It is rated for industrial temperatures from -40°C to +85°C and complies with AEC-Q100 standards.

Feature Summary

• Utilizes MEMS technology for robust performance and high reliability compared to traditional crystal oscillators.
• Offers flexible frequency programming across a wide range from 10 MHz to 460 MHz.
• Integrates enable/disable control functionality for power management optimization.
• Supports HCSL output interface for low-swing differential signaling applications.

Applications

• Telecommunications infrastructure equipment requiring precise clocking.
• Industrial automation systems needing reliable timing signals.
• Automotive electronics compliant with AEC-Q100 standards.
• Data communication interfaces utilizing HCSL logic levels.

Procurement Notes

Verify the specific frequency stability requirement (±10ppm vs ±25ppm) when ordering, as suffixes may denote different accuracy grades within the same package. Confirm that the blank programming state aligns with your design workflow, as external configuration is required before operation. Ensure the 6-VDFN footprint matches your PCB layout constraints. Cross-reference the latest datasheet revision for any updates to electrical characteristics or mechanical dimensions prior to finalizing procurement specifications.

Selection Notes

Select this component when a programmable MEMS solution is preferred over fixed-frequency crystals for design flexibility. Consider the HCSL output type if interfacing with compatible receivers requiring low-voltage swing signals. Evaluate the 42mA maximum current consumption against system power budgets. The AEC-Q100 qualification makes it suitable for automotive environments, while the industrial temperature range supports harsh operational conditions. Verify that the 10MHz-460MHz range covers all necessary clock frequencies for the target application.

Part Context

The DSC8124CI5 belongs to the DSC8124 series of programmable MEMS oscillators from Microchip Technology. This family provides a drop-in replacement for standard crystal oscillators while offering software-programmable frequencies. The series is designed to reduce bill-of-materials complexity by supporting multiple frequencies in a single package. The CI5 suffix typically indicates a specific tape-and-reel packaging option and potentially a defined frequency stability grade within the broader DSC8124 product line.

Replacement Considerations

Direct replacements include other DSC8124 variants such as DSC8124BI2 or DSC8124DI2, provided the frequency stability and output logic requirements are met. Ensure substitute parts maintain the same 6-VDFN footprint and pinout compatibility. Verify that alternative models support the required HCSL output and operating voltage range. Check for equivalent AEC-Q100 certification if automotive compliance is mandatory.
