Operating from 1.8V to 3.3V, it draws a maximum supply current of 7.2 mA and drops to 15 µA in standby (power-down) mode. The standby function lets the system clock gate the oscillator without an external load switch.
Housed in a 2.50mm x 2.00mm 4-SMD no-lead package (0.90mm seated height), the DSC1001DI4-066.5800T fits tight PCB layouts common in engine control units and body controllers.
Sourced through independent distribution channels.
Yes. The DSC1001DI4-066.5800T carries an AEC-Q100 rating, which means it has passed the automotive-grade qualification tests for temperature, reliability, and PPAP.
The MEMS resonator in the DSC1001DI4-066.5800T offers inherently better resistance to shock and vibration compared to quartz crystals. It also eliminates the need for external load capacitors and startup time concerns. The trade-off is that the frequency tolerance and temperature stability may be slightly wider than a high-end quartz TCXO, but for most automotive digital logic and CAN-FD clocking, the MEMS part meets the jitter and accuracy requirements without additional components.
