Product details

AEC-Q100 qualification — where it fits in the vehicle

If your BOM requires a 27.6 MHz clock for a CAN transceiver, Ethernet PHY, or MCU, this part carries the automotive PPAP traceability.

Frequency stability and power — sizing the clock tree

That is tight enough for most CAN and 100BASE-T1 applications without a separate TCXO. When the standby (power-down) function is asserted, the oscillator draws a maximum of 15 µA. This is useful for modules that need to wake on a bus event — the oscillator stays off until the enable pin is driven high, saving battery current in ignition-off states.

Package and footprint — 4-SMD, no lead

The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. It is a standard 4-pad land pattern — no thermal pad, no via-in-pad. The 0.126" x 0.098" footprint matches common 3.2 x 2.5 mm oscillator footprints, so a layout designed for a quartz oscillator in the same package size accepts this MEMS part without a board spin.

Product status is Active.

Frequently asked questions

Is DSC1001CI2-027.6000T AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating.

Can I use this MEMS oscillator to replace a standard quartz crystal oscillator?

Yes, if the original quartz oscillator is a 27.6 MHz CMOS-output XO in a 3.2 x 2.5 mm 4-pad package. The MEMS resonator is pin-compatible with most quartz oscillators of the same footprint and output type. Confirm the supply voltage range (1.8–3.3 V) and enable polarity match your design.
