Product details

22.5792 MHz MEMS XO — ±25 ppm, industrial temp

Rated -40 to 85°C with ±25 ppm stability, so it holds the clock edge across the full industrial temperature band without a separate TCXO or oven. CMOS output at 22.5792 MHz — a standard audio/video sample-rate multiple, so it is a natural fit for HDMI audio clocks, DAC master clocks, or any 44.1 kHz-based sample-rate chain.

Supply range and enable/disable control

Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without a separate regulator — one BOM line serves both logic families.

Frequently asked questions
