Supply voltage spans 2.25V to 3.6V, letting it run directly from a 2.5V or 3.3V rail without an intermediate LDO, and the Enable/Disable function allows the output to be tri-stated for power savings in multi-clock designs.
Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this oscillator fits tight PCB layouts where a standard quartz can-style oscillator would not.
Yes, the DSC1121CL2-025.0000 carries an AEC-Q100 rating, meaning it has passed the automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up.
Functionally yes — it is a drop-in replacement for a 25 MHz quartz XO with CMOS output and Enable/Disable control, provided the PCB footprint matches the 6-SMD, No Lead package (3.20 mm x 2.50 mm). The MEMS resonator offers better shock tolerance and faster start-up than quartz, but the electrical interface (CMOS, 2.25V–3.6V supply) is identical.
