The DSC6101MI2A-019.0000T: The Enable/Disable pin lets you pull the output to high-Z and drop supply current to 80 µA typical — handy for power-gating a clock tree in a battery-backed ECU or a sleep-mode sensor node.
Package and board-fit — 4-VFLGA footprint
That is a 2.0 x 1.6 mm land-grid array — small enough for space-constrained PCBs in automotive ECUs or portable devices. Tape & Reel packaging means it feeds into a pick-and-place machine without manual handling. No special ESD precautions beyond the usual — the MEMS die is sealed in the package, so it is no more sensitive than a standard quartz oscillator during assembly.
