Microchip lists the DSC6122CI2A-00AS as obsolete.
CMOS output drives standard logic inputs directly; the 3 mA max supply current means the thermal budget in a dense VDFN layout is negligible — no airflow or heatsinking required even at 85°C.
The DSC6122CI2A-00AS is obsolete per Microchip.
It is a MEMS-based XO providing two fixed CMOS clock outputs (20 MHz and 25 MHz) for low-power systems, industrial controllers, and battery-operated devices needing a single oscillator to clock multiple logic domains.
