Product details

22.5792 MHz MEMS oscillator for audio and automotive

Supply range and frequency stability

Frequency stability of ±10 ppm holds the audio clock jitter within the tolerance window for 24-bit DACs and ADCs; the MEMS resonator eliminates the warm-up drift of a quartz crystal.

Package and board footprint

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 standard 7x5 mm oscillator footprint that drops onto existing PCB layouts for 22.5792 MHz cans.

Frequently asked questions

Can the DSC1121AE5-022.5792 directly replace a standard 22.5792 MHz crystal oscillator?

The MEMS-based DSC1121AE5-022.5792 is pin-compatible with standard 6-pin oscillator footprints and does not require external load capacitors.

What supply voltage range does the DSC1121AE5-022.5792 support?

The supply range is 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an external regulator.

Is the DSC1121AE5-022.5792 automotive qualified?

Yes, it carries AEC-Q100 rating, meaning it has passed automotive-grade reliability stress testing for temperature, humidity, and vibration.
