Dual-frequency MEMS XO in a 1.6×1.2 mm footprint
The DSC6021HI2A-00A2: The dual-frequency output means one oscillator covers two clock domains — common in mixed-speed designs where a microcontroller runs at 48 MHz and a peripheral bus or USB interface needs 24 MHz — saving a second oscillator slot and the associated PCB area.
