The DSC6001JI2B-016.7772 is an AEC-Q100 qualified MEMS-based XO delivering a 16.7772 MHz CMOS output with ±25 ppm frequency stability across -40°C to +85°C. Supply voltage spans 1.8 V to 3.3 V, so it drops into existing 1.8 V or 3.3 V clock domains without a level translator.
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm — a compact footprint that fits dense multi-layer automotive PCBs. Surface-mount assembly; the small body means the solder paste volume and stencil aperture need to be controlled to avoid tombstoning. No exposed thermal pad, so the primary heat path is through the solder joints to the PCB copper. The 4-pin VLGA layout is standard for MEMS oscillators in this family — the pinout matches the industry-common footprint for 4-pin 2.5 x 2.0 mm oscillators, so a layout designed for a quartz XO in the same package can often accept this MEMS part without a board spin.
