12 MHz MEMS oscillator — commercial temp, CMOS output
The DSC1033DC2-012.0000T is a 12 MHz MEMS-based XO from Microchip's PureSilicon™ series, delivering a CMOS output at 3.3V with ±25ppm frequency stability. The 4-SMD no-lead package (2.50mm x 2.00mm) fits tight board layouts, but the 0.90mm seated height means it sits low enough for card-edge or mezzanine clearance.
Microchip lists the DSC1033DC2-012.0000T as Obsolete. A board spin to a newer MEMS oscillator family (e.g., DSC11xx series) may be the long-term migration path.
Active supply current is 10mA max at 12 MHz — the standby mode preserves battery life in intermittently clocked systems like sensor nodes or remote monitors.
