Product details

That certification is the gate for under-hood and cabin electronics; a non-qualified oscillator would require a separate qualification run, adding weeks to the PPAP timeline.

Standby (Power Down) function and supply current

Active current draw is 6.5 mA max, typical for a 2.048 MHz CMOS oscillator driving a 15 pF load.

4-VDFN package and board fit

Housed in a 4-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Surface-mount reflow profile follows JEDEC MSL-1 typical for MEMS oscillators; no moisture bake needed before assembly if the reel seal is intact.

Frequently asked questions

Is the DSC1001BI1-002.0480T AEC-Q100 qualified?

This makes it suitable for automotive applications such as body control modules, gateway ECUs, and sensor interfaces where a standard commercial oscillator would require a deviation request.

What is the standby function on this oscillator?

The standby (Power Down) function disables the output and reduces supply current to 15 µA max. The pin is typically active-low; pulling it low places the output in high-impedance state. This is useful for power-gated clock domains where the oscillator must not load the bus during sleep.

Can the DSC1001BI1-002.0480T replace a quartz crystal oscillator?

Yes — the MEMS resonator eliminates the quartz crystal's start-up time and mechanical fragility. The CMOS output is directly compatible with most clock inputs. However, confirm the load capacitance and drive strength match the downstream receiver; a quartz oscillator's output is typically a sine wave or clipped sine, while this part outputs a full-swing CMOS rail-to-rail signal.
