DSC8123AI5

Overview

The DSC8123AI5 is an unprogrammed MEMS oscillator from Microchip Technology, designed for high-performance timing applications. It operates within a frequency range of 10 MHz to 460 MHz with a frequency stability of ±10 ppm. The device supports LVDS output format and functions on a supply voltage between 2.25 V and 3.6 V. It features a maximum current consumption of 32 mA and is rated for AEC-Q100 automotive standards. The component operates across an extended temperature range from -40°C to +85°C. It is housed in a compact QFN-4 package measuring 5 mm by 3.2 mm with a seated height of 0.90 mm.

Feature Summary

• AEC-Q100 qualified for automotive reliability requirements
• Unprogrammed blank state requiring user configuration
• LVDS output interface for high-speed signal integrity
• MEMS technology providing robust vibration resistance

Applications

• Automotive infotainment systems
• Telematics control units
• Advanced driver assistance systems (ADAS)
• Industrial communication interfaces

Procurement Notes

Verify the specific suffix codes against official Microchip documentation to confirm package dimensions and tape/reel specifications. Ensure that the unprogrammed nature of the device is accounted for in your manufacturing workflow, as field programming capabilities must be supported by your host system. Cross-reference the AEC-Q100 rating if automotive compliance is mandatory for your final assembly. Confirm lead times directly with authorized distributors as production cycles may vary based on regional demand and supply chain conditions.

Selection Notes

Select this component when a programmable MEMS solution with automotive qualification is required. The wide frequency range allows flexibility in clock generation without maintaining multiple stock keeping units. The LVDS output is suitable for noise-sensitive digital circuits. Consider the 32 mA current draw for power budget calculations. The unprogrammed status offers design flexibility but necessitates integration of programming logic in the end product.

Part Context

This part belongs to the DSC8123 series of programmable MEMS oscillators. It shares architectural similarities with other members like the DSC8123BI5 and DSC8123DI5T, differing primarily in package type and shipping configuration. The AI5 suffix typically denotes the automotive-grade variant with specific packaging constraints. It serves as a drop-in replacement for traditional crystal oscillators in designs requiring precise frequency tuning and high reliability.

Replacement Considerations

Direct substitutes include other DSC8123 variants such as DSC8123BI5 or DSC8123DI5T, provided the package footprint and pinout compatibility are verified. Check datasheets for differences in operating temperature ranges and supply voltage tolerances. Ensure that any replacement maintains the LVDS output format and ±10 ppm stability requirement to preserve system timing integrity.
