This allows the oscillator to sit on a battery-backed rail without draining the cell during long sleep periods."},{"question":"Is DSC1001CI2-037.1250 a direct replacement for a crystal oscillator?","answer":"Yes, it is a form-fit-function replacement for a quartz-based XO in the same 4-SMD package. The MEMS resonator provides better shock and vibration immunity than a quartz crystal, and the CMOS output is directly compatible with most clock inputs."},{"question":"What is the frequency stability of DSC1001CI2-037.1250?","answer":"The frequency stability is ±25 ppm, which includes variations over temperature, supply voltage, and aging.
