MEMS oscillator for 33.3333 MHz clock trees
The DSC6101JL2B-033.3333T: 33.3333 MHz is a common reference for 100/1000BASE-T Ethernet PHYs and USB 2.0 hub controllers — the oscillator provides the master clock without an external crystal or load capacitors.
Typical supply current is 3 mA, low enough that the oscillator adds negligible overhead to the system power budget even in battery-backed designs.
Automotive qualification and deployment context
The MEMS resonator eliminates the aging drift and mechanical shock sensitivity of quartz crystals, a practical advantage in powertrain or chassis-mounted modules.
