The DSC1001DE1-012.2880 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a 12.288 MHz CMOS output with ±50 ppm frequency stability across its -20°C to +70°C operating range. The 4-SMD no-lead package (2.50 mm x 2.00 mm x 0.90 mm) is a compact footprint for space-constrained PCB layouts, common in automotive ECUs and portable devices.
Supply voltage spans 1.8V to 3.3V, covering common digital logic rails without needing an extra regulator — a single supply works across 1.8V, 2.5V, or 3.3V domains.
