The DSC2311KI2-R0061T is a standard XO (Standard) based on a MEMS resonator, delivering two independent CMOS clock outputs: 25 MHz on output 1 and 100 MHz on output 2. This dual-frequency part replaces two single oscillators on the board, saving footprint and BOM line count. Housed in a 6-VDFN package measuring 2.50 mm × 2.00 mm with a 0.90 mm seated height, it fits dense PCB layouts where vertical clearance is tight.
For a 100 MHz clock, ±25 ppm translates to ±2.5 kHz of maximum frequency deviation — tight enough to keep a gigabit Ethernet PHY or a USB 2.0 controller within their PLL capture range without re-centering. The supply voltage spans 2.25 V to 3.6 V, so the same oscillator can be fed from a 2.5 V or 3.3 V rail without a separate regulator.
Active production – no end-of-life watch needed
Microchip lists the DSC2311KI2-R0061T as Active. The base product number DSC2311 covers a family of dual-output MEMS XOs; this specific variant is the 25 MHz + 100 MHz, ±25 ppm, -40°C to 85°C grade.
