Product details

50 MHz MEMS oscillator with wide supply range

Its 2.25V to 3.6V supply range means it can run from a 2.5V or 3.3V rail without a separate regulator — a single supply covers both, simplifying the power tree on a mixed-voltage board.

Enable/Disable and industrial temperature grade

Package and footprint: 6-SMD no lead

Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.126" x 0.098" footprint matches standard 2.5 x 3.2 mm oscillator pads — no via-in-pad or exotic fan-out required. The 50 ppm frequency stability keeps the clock within ±2.5 kHz at 50 MHz across temperature, which is tight enough for most 10/100 Ethernet PHY and MCU main-clock applications.

Frequently asked questions

Does DSC1121CI1-050.0000T have an enable/disable feature?

Yes, it includes an Enable/Disable function. Pulling the enable pin low disables the output, reducing supply current from 35 mA to 22 mA — useful for power-sensitive designs that gate the clock during sleep.
