Supply voltage accepts 2.5V to 3.3V rails, making it a drop-in for common 3.3V or 2.5V clock trees without an external regulator.
The 4-VDFN exposed pad package measures 7.00 mm × 5.00 mm, seated height 0.90 mm max. A via array under the pad helps spread heat and reduce ground inductance.
Microchip lists the DSC1522AI2A-12M80000T as Active — it is in production and suitable for new designs.
The DSC1522AI2A-12M80000T operates from 2.5V to 3.3V. It can run directly from a 3.3V or 2.5V rail without an external LDO.
Yes, it is a MEMS-based XO (Standard) oscillator that is footprint- and function-compatible with many quartz XOs in the same 4-VDFN package. The MEMS resonator eliminates quartz startup jitter and frequency-pulling from board parasitics, but the output is still LVCMOS and the supply range is standard. Confirm the enable polarity and output drive strength against your existing quartz part before substituting.
