With a supply range of 2.25V to 3.6V, it runs directly off a 2.5V or 3.3V rail without an external LDO.
The ±25 ppm frequency stability covers temperature, supply, and aging — tight enough for 10/100 Ethernet, USB full-speed, and general-purpose microcontroller clocking without external trimming.
Yes — the base resonator is MEMS, not a quartz crystal. This gives it better shock/vibration tolerance and faster startup than a quartz-based XO.
It comes in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The 6-pin DFN footprint is common across the DSC2311 family.
Functionally yes — it outputs a standard CMOS clock at 19.2 MHz. The MEMS base resonator means it is more robust to vibration and starts faster than quartz, but the electrical interface (CMOS output, 2.25-3.6V supply) is the same. Confirm the pinout and enable polarity match your board before substitution.
