Rated for -40 to 85°C, it suits industrial environments such as outdoor telecom, factory-floor controllers, and engine-bay electronics where a quartz crystal would need external trim capacitors. A standby (power-down) function drops supply current to 1 µA max when disabled, useful for battery-backed systems that gate the clock to save power. Microchip has marked the DSC1028CI2-026.0000T as Obsolete. Available through independent surplus distribution in lot-specific quantities. Pricing and availability are confirmed at RFQ; no stock-holding claim is made here. No official successor or pin-compatible replacement is listed by Microchip for this exact order code. A board-level redesign with a current-generation MEMS oscillator may be required for long-term production. ## Key ratings for BOM fit Frequency stability of ±25 ppm over the full temperature range means the clock uncertainty is low enough for a 26 MHz MCU core or USB interface without external tuning. Maximum supply current is 3 mA typical at 2.8 V — the oscillator's draw is negligible in a system that already burns tens of milliamps, but the 1 µA standby current matters for a sleep-mode power budget.","metaTitle":"DSC1028CI2-026.0000T MEMS XO – 26 MHz, CMOS","metaDescription":"Microchip DSC1028CI2-026.0000T MEMS oscillator, 26 MHz CMOS output, ±25 ppm stability, -40 to 85°C.
