22.5791 MHz MEMS oscillator — why this frequency matters
The DSC1101CI5-022.5791T: 22.5791 MHz is the standard audio sample-rate clock — 44.1 kHz × 512 = 22.5792 MHz, so this oscillator lands right on the master clock for CD-quality audio DACs, ADCs, and S/PDIF transceivers. The CMOS output connects directly to most MCU clock inputs and audio codec reference pins — no external level translation needed.
Supply voltage and standby — fitting the power budget
The wide range also tolerates a battery drooping under load, which matters for portable audio gear.
This oscillator is at home in outdoor telecom cabinets, factory-floor audio systems, or engine-adjacent enclosures where a commercial-grade part would drift out of spec.
Active product status — no last-time-buy deadline, no end-of-life pressure.
