The DSC1121NE2-025.0000T is a 25 MHz MEMS-based XO (standard oscillator) from Microchip's DSC1121 series, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range.
Supply voltage and frequency stability for BOM fit
Operating from 2.25V to 3.6V, the oscillator can share a 2.5V or 3.3V rail without an extra LDO — useful when the MCU or SoC already supplies that voltage. The ±25 ppm stability covers temperature, supply, and aging effects, which is sufficient for most 25 MHz clock trees in CAN, LIN, or basic Ethernet PHYs.
