DSC8123DI2

Overview

The DSC8123DI2 is an unprogrammed MEMS oscillator manufactured by Microchip Technology, housed in a compact 6-SMD, No Lead package. It operates within a supply voltage range of 2.25 V to 3.6 V and supports frequencies from 10 MHz to 460 MHz. The device features LVDS output format with a maximum duty cycle of 52% and offers frequency stability options including ±10 ppm and ±25 ppm variants. It is designed for industrial applications with a specified operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes MEMS technology for high reliability and low phase jitter performance
• Supports LVDS output interface for high-speed signal integrity
• Includes enable/disable functionality for power management optimization

Applications

• Industrial control systems requiring precise timing
• Communication equipment utilizing LVDS interfaces
• Embedded systems needing stable clock sources

Procurement Notes

Verify the specific frequency stability requirement (±10 ppm or ±25 ppm) when ordering, as the base model number may refer to the series rather than a single fixed specification. Confirm the package type matches the PCB footprint requirements. Ensure the operating temperature range aligns with the application environment. Check for RoHS compliance status if environmental regulations apply. Validate the supply voltage compatibility with the target system design.

Selection Notes

Select this component when a small form factor MEMS oscillator with LVDS outputs is required. Consider the ±10 ppm variant for higher precision needs or ±25 ppm for cost-sensitive designs. Ensure the 2.25 V to 3.6 V supply range fits the system power architecture. Evaluate the thermal performance against the -40°C to +85°C operational limits. Compare against other DSC8123 family members for pin compatibility and feature sets.

Part Context

The DSC8123DI2 belongs to the DSC8123 series of programmable MEMS oscillators from Microchip Technology. This series is characterized by its small footprint and robust performance in demanding environments. It serves as a direct replacement for traditional quartz oscillators in space-constrained designs. The DI2 suffix typically indicates a specific package configuration and temperature rating within the product line.

Replacement Considerations

Direct substitutes include other DSC8123 series variants such as DSC8123BI5 or DSC8123DI5T, provided the package and electrical specifications match. Verify that any replacement maintains the same LVDS output format and frequency stability. Cross-reference the pinout and dimensions to ensure mechanical compatibility.
