Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-configured frequency code associated with the R0012 suffix directly with Microchip or authorized distributors. Confirm that the required operating temperature range aligns with the Industrial specification (-40 °C to +85 °C). Ensure the design accommodates the 6-lead VDFN package dimensions and recommended land pattern for proper soldering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a compact, high-reliability clock source is needed without external crystals. Consider the ±25 ppm stability requirement and the 2.3 MHz to 170 MHz frequency range. Verify that the CMOS output format meets the input requirements of the downstream logic devices. Check if the single bypass capacitor requirement fits the board space constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the DSC2311 family of crystal-less clock generators. Other variants in the series offer different temperature ranges, such as Automotive (-40 °C to +125 °C) or Extended Commercial (-20 °C to +70 °C), and varying stability options like ±50 ppm. The KI2 suffix specifically denotes the Industrial temperature grade and ±25 ppm stability.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 6-lead VDFN package and CMOS output type. Cross-reference with other DSC2311 variants if temperature or stability requirements differ. Verify pin compatibility and electrical characteristics against the original datasheet specifications before substitution.
