The DSC6101MA3B-026.0000: The surface-mount MEMS resonator inside means no quartz crystal to crack under vibration, and the 4-pin LGA is straightforward to reflow with standard profiles. Pin 1 is marked by a chamfered corner on the package body — visible under magnification, so orientation is clear during hand placement or pick-and-place.
The MEMS-based design eliminates quartz supply constraints and the package is a standard 4-VFLGA, so second-source options from the same family are available if needed — confirm pin compatibility at RFQ.
