MEMS oscillator at 6.78 MHz — what it clocks
The DSC1004DI1-006.7800T: This is a Microchip DSC1004-series MEMS oscillator locked to 6.78 MHz — a common frequency for USB controllers, baseband processors, and certain CAN transceiver reference clocks. The CMOS output swings rail-to-rail across the full 1.8V to 3.3V supply range, so it mates directly with 1.8V or 3.3V logic without a level shifter.
AEC-Q100 — built for the car
Housed in a 4-SMD, no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm. The small footprint suits space-constrained PCBs in telematics modules, camera ECUs, or sensor nodes.
