The DSC1101CI1-050.0000T is a 50 MHz XO (Standard) clock generator built around a MEMS resonator rather than a quartz crystal — the MEMS die is sealed at wafer level, which gives it better shock and vibration immunity than a bulk crystal in the same 3.2 mm × 2.5 mm 6-SMD no-lead package. The supply voltage range spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails from a single part number — useful when the same BOM must populate boards for different voltage domains.

Frequently asked questions
What is the difference between DSC1101 and DSC1121?
The DSC1121 is a higher-performance sibling in the same MEMS oscillator family, typically offering tighter frequency stability options (e.g., ±10 ppm or ±25 ppm) versus the DSC1101's ±50 ppm. Both share the same 6-SMD package and pinout, so a board designed for the DSC1101 can accept the DSC1121 as a drop-in upgrade if the application needs tighter timing margin.
