The supply voltage range spans 2.25V to 3.6V, so the oscillator runs directly from a 2.5V or 3.3V rail without an intermediate LDO.
The 6-SMD No Lead package measures 2.50mm x 2.00mm (0.098" x 0.079") with a seated height of 0.90mm, a compact footprint that fits tight PCB layouts without the height penalty of a through-hole can.
26 MHz.
Yes, the part has an Enable/Disable function that allows the output to be gated.
A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. MEMS oscillators are generally more resistant to vibration and shock, and they start up faster than quartz-based oscillators. The DSC1121 family is built on a MEMS resonator.
No spread spectrum capability is listed in the available specifications for this part number.
