Product details

22.5792 MHz MEMS clock — what it replaces and why

The DSC1121BI2-022.5792T is a MEMS-based XO (Standard) oscillator delivering a 22.5792 MHz CMOS output — a frequency commonly required by audio DACs, video scalers, and network synchronisation blocks that need a non-standard multiple of 44.1 kHz.

Wide supply range and enable/disable function

Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator — useful when the same BOM position serves multiple board variants.

Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a common footprint shared with many quartz and MEMS oscillators, so a board layout designed for a standard 5×3.2 mm clock can mount this part without a spin.

Frequently asked questions

Where can I buy DSC1121BI2-022.5792T and how is it quoted?

No stock-holding claim is made; each order is placed per your requirement.

What is the frequency stability of the DSC1121BI2?

The DSC1121BI2-022.5792T is specified with a frequency stability of ±25 ppm over its full operating temperature and supply range. This is tight enough for most audio and video clocking applications without needing a temperature-compensated oscillator.

Can this MEMS oscillator replace a quartz oscillator on my board?

Yes — the DSC1121BI2-022.5792T is pin-compatible with many standard 5×3.2 mm 6-pin quartz oscillators. The MEMS resonator offers better shock and vibration tolerance, and the supply range (2.25 V to 3.6 V) covers common logic rails. Confirm the footprint and enable/disable logic polarity against your existing quartz part before committing.
