The DSC1001CE5-012.2880 is a Microchip MEMS-based standard oscillator (XO) delivering a 12.288 MHz CMOS output with ±10 ppm frequency stability across its -20°C to 70°C operating range. Rated AEC-Q100, this part carries automotive-grade qualification — the OEM auditor will ask for PPAP documentation tied to the grade; the 1.8V to 3.3V supply range makes it compatible with common automotive logic rails.
Supply Range and Standby Function
Wide 1.8V to 3.3V supply covers 2.5V and 3.3V automotive domains without an external level translator; the standby (power-down) function pulls the output to high-impedance, reducing current draw to near-zero during sleep modes. Maximum supply current is 6.5 mA at full load — well within the budget of a 3.3V automotive ECU rail.
