The DSC1001CI2-019.4400T: Its 1.8V to 3.3V supply range means it can run directly from a 1.8V core rail or a 3.3V I/O rail without an external regulator — a single BOM line covers multiple voltage domains.
Yes, it carries AEC-Q100 qualification, making it suitable for automotive applications that require the extended reliability and temperature cycling of that standard.
Yes, it is a drop-in replacement for a standard 19.44 MHz quartz XO with CMOS output, same 4-SMD package footprint. The MEMS construction offers better shock and vibration tolerance than quartz, and the ±25 ppm stability meets typical quartz specs.
When the standby (power-down) function is active, the maximum supply current is 15 µA.
