Product details

The DSC1121AE5-024.5760 is a MEMS-based XO (Standard) oscillator delivering a 24.576 MHz CMOS output with ±10 ppm frequency stability across its -20°C to +70°C operating range. Supply voltage spans 2.25V to 3.6V, allowing single-rail operation from 2.5V or 3.3V buses without an external regulator.

6-SMD package and board-fit cues

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm x 0.90mm — a standard footprint that aligns with common quartz oscillator pads, simplifying drop-in replacement. Surface-mount assembly; the exposed pad provides thermal relief but is not electrically required — layout can share the same land pattern as a standard 7x5 mm SMD oscillator.

Frequently asked questions

Is the DSC1121AE5-024.5760 obsolete or end-of-life?

It remains suitable for both new designs and production replenishment.

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

Within the same DSC1121 series, the DSC1121AE5-025.0000 is a 25.000 MHz variant in the identical package and pinout. The only difference is the output frequency — all other ratings (supply, stability, temperature range) match.
