Product details

The DSC1121AI5-100.0000: The supply voltage spans 2.25V to 3.63V, covering 2.5V and 3.3V rails without an external regulator, and the enable/disable function lets the system gate the clock when the downstream peripheral is idle.

Package and footprint – 6-SMD no-lead exposed pad

Housed in a 6-SMD no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the oscillator mounts on standard surface-mount pads with a thermal pad underneath for heat sinking.

Lifecycle and design-in posture

No PCN or EOL notice is recorded for this order code; the base product number DSC1121 covers a family of MEMS oscillators, and the 100.0000 suffix confirms the fixed output frequency.
