The DSC6101JI3B-100.0000T: The MEMS base eliminates quartz-specific failure modes — no startup reliability concerns, no shock-induced frequency jumps, and no crystal aging drift over the first year of field operation.
At 3 mA typical supply current, the oscillator's draw is negligible in a 1A automotive power budget — the same LDO feeding the MCU core can also supply this clock without derating. Pull the enable pin low to stop oscillation and drop the supply current to near-zero — useful for modules that must pass a low-quiescent-current sleep test per OEM specification.
The 4-pin land pattern is standard for MEMS oscillators in this footprint — no special via-in-pad or thermal relief required. The CMOS output drives a standard 15 pF load; route the clock trace with a 50-ohm characteristic impedance if the trace length exceeds 25 mm to avoid edge reflections at 100 MHz.
