MEMS oscillator for precise 49.152 MHz timing
The DSC1101CE2-049.1520 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a 49.152 MHz CMOS output with ±25 ppm frequency stability across its operating range. It operates from a 2.25V to 3.6V supply rail, drawing a maximum of 95 µA — low enough for battery-powered or always-on subsystems where the oscillator must not dominate the power budget.
Housed in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1101CE2-049.1520 fits standard oscillator footprints for 3.2 x 2.5 mm XO patterns.
