The DSC1101NI2-025.0000 is a 25 MHz XO (Standard) oscillator built around a MEMS resonator, not a quartz crystal — the MEMS die is sealed at wafer level, which eliminates the quartz cold-start and vibration sensitivity issues that can pull a crystal oscillator off frequency in a high-shock environment. Rated over -40 to 85°C with ±25 ppm frequency stability, it holds the clock edge within a tight window across the industrial temperature band — a motor drive or outdoor telecom card that sees 85°C on a summer afternoon still meets its bit-error budget. Supply voltage spans 2.25V to 3.6V, so the same oscillator works on a 2.5V FPGA bank and a 3.3V MCU rail without a separate regulator — one BOM line covers both domains.
Active draw is 35 mA max at 25 MHz — the CMOS output swings rail-to-rail into a 15 pF load, so the actual current depends on the downstream input capacitance and toggle rate.
6-VDFN package, 7.00 x 5.00 mm body, 0.90 mm seated height — the land pattern is a standard 6-pad DFN with a centre thermal pad that should be tied to the ground plane for heat sinking.
