Product details

MEMS timing for industrial boards

Because the resonator is MEMS rather than quartz, it shrugs off the vibration and shock that can pull a crystal off-frequency in a motor drive or a panel that gets shipped on a pallet.

Supply voltage and power-down

The standby (power-down) function drops current consumption to 95 µA max when the clock is not needed, letting you gate the oscillator with a GPIO instead of adding a load switch.

Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, it fits the same footprint as many standard 3.2 x 2.5 mm quartz oscillators. The 35 mA max supply current at 20 MHz is typical for a MEMS oscillator driving a CMOS load; no special thermal relief is needed on the PCB.

Frequently asked questions

How can I order the DSC1101CI5-020.0000 or check availability?

Submit an RFQ for current pricing and lead time confirmation.

Can the DSC1101CI5-020.0000 replace a standard 20 MHz crystal oscillator?

Yes, in most cases. The DSC1101CI5-020.0000 outputs a 20 MHz CMOS clock with ±10 ppm stability, which matches or exceeds the accuracy of a typical quartz crystal oscillator. The MEMS resonator is more shock-tolerant, and the 6-SMD footprint is common.

Is the DSC1101CI5-020.0000 compatible with 3.3 V logic?

Yes. The supply range of 2.25 V to 3.6 V covers 3.3 V operation, and the CMOS output swings rail-to-rail, so it drives 3.3 V logic inputs directly.

What are the pin functions of the DSC1101CI5-020.0000?

The 6-SMD no-lead package includes power (VDD), ground (GND), clock output (OUT), and a standby (PD) pin that disables the output and drops current to 95 µA when pulled low. The remaining two pins are no-connects (NC) or may be used for factory test — refer to the DSC1101 series datasheet for the exact pinout diagram.
