The MEMS resonator provides faster start-up and better shock resistance than quartz-based oscillators, a practical advantage in engine-bay and chassis-mounted modules.
Supply voltage range and standby power-down
The supply voltage range spans 1.8V to 3.3V, allowing the oscillator to operate from a single 1.8V, 2.5V, or 3.3V rail without an external regulator — useful when the same BOM must support multiple voltage domains. Active current draw is 7.2 mA max, a typical figure for a 29.4912 MHz CMOS oscillator at 3.3V; the low disable current makes the part viable for always-powered automotive modules that spend most of their time in standby.
Package, footprint, and mounting
Housed in a 4-SMD, No Lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm, the DSC1001DI5-029.4912T fits compact PCB layouts common in automotive ECUs and sensor modules. Surface-mount assembly with a standard reflow profile; the small footprint leaves room for adjacent decoupling capacitors and signal routing on dense boards.
