The 72 MHz output is a common reference for automotive Ethernet PHYs, MCU clock trees, and infotainment SoCs. The ±25 ppm stability keeps the timing budget tight enough for CAN-FD and 100BASE-T1 without an external TCXO.
The supply range of 1.8V to 3.3V means it can run directly from a 1.8V MCU rail or a 3.3V peripheral bus without a level translator.
Yes, the DSC1004DI2-072.0000T carries an AEC-Q100 rating, which means it has passed automotive-grade qualification including temperature cycling, ESD, and reliability stress tests.
The output is CMOS at 72 MHz. The ±25 ppm frequency stability covers temperature and aging, making it a drop-in reference for most MCU and PHY clock inputs.
For sustained ambient above 85°C, a different oscillator with a wider temperature range would be needed.
