That 400:1 ratio means the oscillator can be gated off between CAN bus wake-up cycles without a dedicated load switch — the enable pin on the MEMS die handles it. For a battery-backed module that sleeps 99% of the time, the standby current is below the self-discharge floor of a typical coin cell.
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.
The oscillator outputs a 12.8 MHz CMOS signal. CMOS levels are compatible with 1.8V, 2.5V, and 3.3V logic families without external level translation, as long as the supply voltage matches the I/O rail.
Yes. The part includes a Standby (Power Down) function that reduces supply current to 15 µA max when the enable pin is de-asserted. The output goes high-impedance in standby, so the downstream clock input sees a tri-state condition — ensure the receiver has a pull-down or a failsafe clock-detection circuit.
