Product details

20 MHz MEMS XO with automotive-grade qualification

Rated across -40°C to +85°C with ±10 ppm frequency stability, this oscillator keeps the clock edge within tight tolerance for a CAN bus or a 10/100 Ethernet PHY reference — the kind of rail that doesn't tolerate drift. Supply voltage spans 1.7V to 3.6V, so it runs from a 1.8V core rail or a 3.3V I/O rail without an extra LDO. The 6 mA max supply current at 20 MHz is low enough that a small 100 nF decoupling cap at the Vdd pin is sufficient — no bulk electrolytic needed.

Standby power-down for battery-backed designs

That is the difference between a coin cell lasting a month versus a year in a remote sensor that sleeps most of the time.

AEC-Q100 qualification and active production

It is suitable for under-hood, cabin, or chassis-domain ECUs where the ambient temperature hits 85°C and the board sees vibration. Product status is Active.

Frequently asked questions

What is the exact frequency of DSC1003CI5-020.0000?

20.0000 MHz — the order code suffix encodes the frequency, so this is a fixed-output oscillator with no external tuning components.

Is DSC1003CI5-020.0000 suitable for automotive applications?

The MEMS resonator also withstands the shock and vibration profile of an engine bay or transmission-mounted ECU better than a quartz crystal.

How does the standby power-down function work on DSC1003CI5-020.0000?

The Standby (Power Down) function disables the output and reduces supply current to 15 µA max. The oscillator stops oscillating internally; the output goes high-impedance. Asserting the enable pin restarts the oscillator — the MEMS resonator starts within microseconds, unlike a quartz crystal that can take milliseconds to stabilise.

What is the standby current of DSC1003CI5-020.0000?

15 µA max — this is the current drawn when the Standby (Power Down) function is active. It allows the oscillator to be left connected to a battery-backed rail without draining it.
