The DSC1101CM1-005.0000 is a 5 MHz MEMS-based XO (Standard) with CMOS output, housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm.
Supply voltage and power management
Supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails directly — no external LDO needed for voltage translation. For battery-powered sensors or IoT nodes that duty-cycle the clock, this disable current is low enough to leave the oscillator powered through a sleep state without draining the cell.
Frequency stability and timing margin
For a 5 MHz clock, ±50 ppm translates to a maximum frequency error of 250 Hz — well within the tolerance for most MCU crystal inputs and UART baud-rate generators, but worth checking if the downstream PLL has a narrow capture range.
