Product details

3.6864 MHz MEMS oscillator with automotive-grade qualification

AEC-Q100 qualification means this oscillator has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — making it suitable for under-hood and chassis-domain electronics where a standard quartz oscillator would not be accepted without additional screening. The MEMS resonator core inherently withstands higher shock and vibration than a quartz crystal, and its start-up time is typically under 5 ms — a practical advantage in automotive key-fob or engine-control modules that must wake and lock fast.

Standby power-down and supply flexibility

A standby (power-down) pin drops the supply current to 15 µA max when asserted — the oscillator stops and the output goes high-impedance. For a battery-backed ECU or a sensor node that sleeps most of the time, this leakage floor is low enough to ignore in the sleep-state budget. The supply voltage range spans 1.8V to 3.3V, so the same part can be powered from a 1.8V core rail, a 2.5V I/O rail, or a 3.3V peripheral rail without a dedicated LDO. This simplifies the power tree and reduces BOM line count in multi-rail designs.

Active lifecycle and sourcing through independent distribution

It is available for new designs and volume replenishment through independent distribution, quoted to order against the BOM quantity.

Frequently asked questions

Is the DSC1001BI1-003.6864T AEC-Q100 qualified?

Yes, the DSC1001BI1-003.6864T carries an AEC-Q100 rating, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. This qualifies it for under-hood and chassis-domain applications where a standard commercial oscillator would not be accepted.

What is the standby current consumption of the DSC1001BI1-003.6864T?

When the standby (power-down) pin is asserted, the oscillator stops and the supply current drops to 15 µA maximum. This is the leakage floor in sleep mode — low enough for battery-backed automotive ECUs or always-on sensor nodes.

Does the DSC1001BI1-003.6864T have a standby pin?

Yes, the function is listed as Standby (Power Down). Asserting this pin stops the oscillator and puts the output into high-impedance state, reducing current draw to 15 µA max.
