The DSC1033BI1-008.0000T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a fixed 8 MHz CMOS output from a 3.3V rail with ±50ppm frequency stability across -40°C to 85°C. The MEMS resonator replaces a quartz crystal — no external load capacitors needed, and the part survives higher shock and vibration than a crystal-based oscillator. The standby (power-down) function drops supply current to 1µA max, useful for battery-powered equipment that sleeps between active cycles.
Microchip lists the DSC1033BI1-008.0000T as Obsolete. It is not recommended for new designs. No official successor or pin-compatible replacement is recorded from the original manufacturer. Available through independent surplus distribution in lot-specific quantities. Availability and pricing confirmed at RFQ — no stock-holding claim.
