Dual-output MEMS oscillator for clock trees
The DSC6121ML3B-01QHT: This dual-output architecture eliminates a second oscillator footprint and the associated routing, saving board area in space-constrained designs like automotive camera modules or sensor fusion ECUs where the 1 MHz drives a watchdog or CAN controller and the 64 MHz feeds the main MCU core.
Automotive temperature grade and supply tolerance
Typical current draw is 3 mA max, low enough that the oscillator's contribution to the thermal budget is negligible even in a sealed module with no airflow.
