Dual-frequency MEMS XO with wide supply tolerance
The DSC6122CI2A-00B0: Typical current draw is 3 mA max — the MEMS die consumes less than a quartz equivalent at these frequencies, which matters for power-budgeted portable or sensor-node designs.
4-VDFN package — board-fit checklist
The 4-pin footprint is standard for MEMS oscillators of this class — the supply decoupling cap sits close to the VDD pin, and the enable pin (OE/STDBY) should be tied high or low per the datasheet logic to avoid an undefined state. No exposed pad; the thermal path is through the package body to the board.
