The DSC1101CI1-008.0000T uses a MEMS resonator rather than a quartz crystal — the base resonator is MEMS, so the oscillator survives 50,000 g shock and 70 g vibration without the frequency jump a quartz blank can exhibit under mechanical stress. For a panel-mount controller or a portable instrument that gets dropped, the MEMS construction keeps the clock alive where a quartz XO might glitch.
Standby mode for duty-cycled designs
A battery-powered sensor that sleeps 99 % of the time burns 95 µA in standby instead of 35 mA, extending shelf life by orders of magnitude without an external load switch.
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 same footprint as a standard 3.2 x 2.5 mm quartz oscillator, so it drops onto an existing PCB layout without a board spin. The no-lead construction reduces parasitic inductance compared to a gull-wing package, keeping the 8 MHz CMOS edge clean.
