The DSC1001DL2-033.0000T is a 33 MHz XO (Standard) from Microchip's DSC1001 series, built on a MEMS resonator with a CMOS output — a drop-in clock source for MCUs, FPGAs, and automotive ECUs that need a clean square wave without an external crystal and load caps. Rated over -40°C to 105°C with ±25 ppm frequency stability, it holds timing across the full industrial and automotive ambient range — the AEC-Q100 qualification (cite:) confirms it for under-hood and chassis-domain designs where vibration and temperature swings are the norm.
Operates from a single 1.8V to 3.3V rail, covering the three most common logic supplies — no separate regulator needed when the MCU runs at 3.3V or the core at 1.8V. Maximum supply current is 7.2 mA during active oscillation; the standby (power-down) function drops draw to 15 µA max, letting the system gate the clock on low-power sleep states without a discrete load switch.
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the compact footprint fits tight layouts in ADAS modules, telematics units, or portable instrumentation where board real estate is at a premium.
