DSC2311KI2-R0055

Clock Generators, PLLs, Frequency Synthesizers Overview

The DSC2311KI2-R0055 is a Crystal-less™ configurable clock generator manufactured by Microchip Technology. It utilizes silicon MEMS technology to provide low jitter performance without requiring an external quartz crystal. The device supports output frequencies ranging from 2.3 MHz to 170 MHz with a frequency stability of 25 ppm. It operates on a supply voltage between 2.25 V and 3.6 V, typically 3.3 V, and features CMOS output format. The component is housed in a compact VSON-6 package (2.5 mm x 2 mm) and is rated for an industrial operating temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix R0055 against official Microchip documentation to confirm the exact output frequency configuration, as this code defines the factory-programmed parameter set. Ensure compatibility with the required 3.3V supply and VSON-6 footprint during procurement planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a low-jitter, crystal-free solution is required for frequencies up to 170 MHz. Compare the 25 ppm stability against applications requiring tighter tolerances, such as those needing 10 ppm or lower, which may require alternative series like the DSC2110.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the DSC2311 family of programmable oscillators. These devices are designed to replace traditional quartz crystals and oscillators, offering design flexibility through configurability while maintaining a small form factor ideal for space-constrained PCB layouts.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other DSC2311 variants with different frequency codes (e.g., DSC2311KI2-R0007). Verify that any replacement maintains the same VSON-6 package and 25 ppm stability specification.
