Product details

Active MEMS oscillator – 24 MHz, ±10 ppm, wide supply range

Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails directly, and the Enable/Disable function lets the output be gated off without cycling the power rail.

Package, footprint, and rework considerations

Housed in a 6-SMD no-lead package measuring 5.00 x 3.20 mm with a seated height of 0.90 mm — the low profile suits tight enclosures, but the no-lead terminations mean the solder joint is hidden under the body after reflow. Will it survive the hot air? Yes — the MEMS resonator is less thermally massive than a quartz crystal, so the package reflows evenly with a standard lead-free profile. Just watch the soak time: the 0.90 mm height means the body heats fast, and the no-lead pads need enough paste volume to form a visible fillet at the side. Pin 1 orientation is marked on the package — confirm the pad layout matches the 6-SMD no-lead footprint before committing the board; a misaligned pad pattern lifts the part, not the pad.

Frequently asked questions

What is the closest pin-compatible alternative in the DSC1121 family?

The DSC1121 series shares the same 6-SMD no-lead package and pinout across frequency variants. A different frequency (e.g., 25 MHz or 50 MHz) with the same ±10 ppm stability and CMOS output would be footprint-compatible, provided the supply voltage range matches.
