DSC8102CI2

Overview

The DSC8102CI2 is a field-programmable silicon MEMS-based oscillator featuring LVPECL output. It operates within a frequency range of 10 MHz to 460 MHz, with resolution increments of 100 Hz. The device supports supply voltages from 2.25 V to 3.6 V and functions across an industrial temperature range of -40 °C to +85 °C. It utilizes a 3.2 mm x 2.5 mm surface-mount package. Key electrical characteristics include low integrated phase noise jitter of less than 3 ps rms (12 kHz to 20 MHz) and less than 1 ps rms (100 kHz to 20 MHz).

Feature Summary

• Field-programmable silicon MEMS technology for customizable clock generation.
• LVPECL differential output format ensuring high-speed signal integrity.
• Ultra-low integrated phase noise performance for precision timing applications.
• Compact industry-standard surface-mount packaging suitable for dense layouts.

Applications

• High-performance networking equipment requiring precise clock synchronization.
• Telecommunications infrastructure utilizing differential signaling standards.
• Industrial control systems operating in extended temperature environments.
• Data acquisition systems demanding low-jitter clock sources.

Procurement Notes

Verify the specific ordering suffix to confirm the programmed frequency and output configuration, as the base part number denotes the programmable family rather than a fixed specification. Ensure compatibility with the TIMEFLASH programmer for final configuration. Confirm that the LVPECL output voltage levels match the receiving circuitry requirements. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Validate the package dimensions against the PCB footprint design.

Selection Notes

Select this component when differential LVPECL signaling is required for noise immunity in high-frequency designs. Consider the MEMS construction for superior shock and vibration resistance compared to traditional crystal oscillators. Evaluate the need for field programmability to allow post-manufacturing frequency adjustments. Assess the power supply constraints to ensure operation within the 2.25 V to 3.6 V range. Verify that the thermal environment falls within the specified industrial temperature limits.

Part Context

The DSC8102 belongs to Microchip's family of programmable MEMS oscillators, offering flexibility in clock generation. It is electrically identical to the DSC1102 series, allowing for potential cross-referencing in design reviews. The device replaces discrete clock generator solutions by integrating frequency synthesis and output buffering into a single compact package. This integration reduces board space and simplifies the bill of materials for complex electronic systems.

Replacement Considerations

The DSC1102 series is electrically identical to the DSC8102. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement part supports the required LVPECL output format and frequency range.
