DSC1003CI5-025.0000 is a MEMS-based silicon oscillator designed for high-reliability clock generation in industrial, automotive, and consumer electronics.

Manufactured by Micrel (now Microchip Technology), this component replaces traditional quartz crystals with a silicon resonator, offering superior resistance to shock, vibration, and thermal stress.

Core Functionalities

1. Precision Clock Generation
   • Delivers a stable 25MHz output frequency with ±10ppm stability over the industrial temperature range (-40°C to +85°C).
   • Employs MEMS (Micro-Electro-Mechanical Systems) technology to eliminate quartz crystal fragility, ensuring long-term reliability in harsh environments.
2. Wide Operating Range
   • Supports 1.8–3.3V supply voltages, compatible with diverse system architectures.
   • Maintains low power consumption: 6mA active current and 15µA standby current (via an enable pin), ideal for battery-powered devices.
3. Robust Electrical Performance
   • Features CMOS output with 25pF load capacitance (inferred from "CI5" suffix), ensuring clean signal integrity for microcontrollers and FPGAs.
   • Achieves <10ps RMS period jitter at 100MHz (scalable to 25MHz), critical for high-speed data buses like PCIe and Ethernet.
4. Thermal Stability
   • Operates reliably across -40°C to +85°C, meeting EN 60721-3-3 Class 3K3 standards for industrial environments.
   • Exhibits minimal frequency drift (<±5ppm) over temperature, outperforming quartz-based oscillators in thermal cycling conditions.
5. Space-Efficient Design
   • Housed in a 4-pin SMD package (3.2mm x 2.5mm x 1.1mm), enabling compact PCB layouts for portable and embedded systems.

Typical Applications

1. Industrial Automation
   • PLCs and Motor Controls: Provides timing for variable-frequency drives (VFDs) and motion controllers, ensuring synchronization in factory automation.
   • Process Monitoring: Powers sensors and data loggers in oil/gas or chemical plants, with vibration resistance compliant with IEC 61131-2.
2. Automotive Electronics
   • ECU and ADAS Systems: Generates clocks for radar, LiDAR, and infotainment modules, supporting 12V/24V automotive electrical systems.
   • Telematics Units: Stabilizes GPS and cellular communication timing in connected vehicles, meeting AEC-Q200 Grade 2 requirements (pending manufacturer confirmation).
3. Consumer Electronics
   • Smart Home Devices: Drives Wi-Fi/Bluetooth radios in IoT hubs and smart speakers, balancing low power and high stability.
   • Wearables: Enables precise timing for health monitors and fitness trackers, with standby mode optimizing battery life.
4. Communications Infrastructure
   • Network Switches: Synchronizes 1G/10G Ethernet PHYs and PCIe Gen3 interfaces, aligning with IEEE 1588 PTP for telecom-grade timing.
   • 5G Base Stations: Supports RF signal processing in small cells, with wide voltage tolerance for remote deployments.
5. Medical Equipment
   • Diagnostic Tools: Provides low-jitter clocks for MRI scanners and lab analyzers, adhering to IEC 60601-1 safety standards.
