The DSC1001CI2-074.2500 is a fixed-frequency MEMS-based XO (Standard) delivering a 74.25 MHz CMOS output — a common clock rate for video interfaces, Ethernet PHYs, and automotive camera modules. AEC-Q100 qualification confirms it meets the reliability stress and temperature cycling requirements for automotive-grade applications.
The 1.8V to 3.3V supply range lets the oscillator run directly from a 1.8V core rail or a 3.3V I/O rail without an external regulator — a single BOM line serves both voltage domains. Active current is 8.7 mA max, and the standby (power-down) function drops the disable current to 15 µA max, preserving battery life in sleep-mode designs. Frequency stability is ±25 ppm across the full temperature and supply range — tight enough for 100BASE-TX Ethernet and 720p/1080i video pixel clocks without external trimming.
