The DSC1001AI2-066.0000T: This is a 66 MHz MEMS-based oscillator (XO) delivering a CMOS output — a direct-fit clock source for automotive ECUs, ADAS modules, or industrial controllers that need a stable reference without a quartz crystal's startup and aging quirks.
Runs on any rail from 1.8V to 3.3V — no separate regulator needed when the logic side is 1.8V or 3.3V.
Housed in a 7.00 mm × 5.00 mm 4-SMD package with no-lead exposed pad — the pad under the package aids thermal conduction to the PCB. Seated height is 0.90 mm, thin enough for mezzanine card clearance.
