12.5 MHz MEMS oscillator with standby power-down
The DSC1101BE1-012.5000T is a 12.5 MHz MEMS-based XO from Microchip's DSC1101 series, delivering a CMOS output from a 2.25V to 3.6V supply rail. The standby (power-down) function drops supply current to a maximum of 95 µA, making this oscillator suitable for battery-operated equipment that needs to conserve power during idle periods. Rated for -20°C to 70°C operation, it fits commercial and light-industrial environments such as networking gear, industrial control panels, and test equipment.
MEMS resonator and CMOS output
The base resonator is MEMS rather than quartz, which provides inherent resistance to shock and vibration — a practical advantage in portable or mechanically stressed assemblies. Frequency stability is held to ±50 ppm, which is adequate for most UART, SPI, and general-purpose clocking tasks without needing a TCXO. The 6-SMD No Lead package (5.00mm × 3.20mm footprint, 0.90mm seated height) is a standard oscillator land pattern, compatible with automated pick-and-place and reflow soldering.
