Selection Guidance

For industrial controllers and field-bus interfaces designs, confirm the DSO221SY frequency stability and phase-noise profile against your receiver acquisition window. The 1.6–3.6 V supply envelope supports direct interface with common logic families, and the 2.5x2.0x0.9 footprint simplifies PCB layout in dense timing chains.

Validate the start-up time and steady-state current draw against your power budget, and confirm the supply-pushing and load-pulling behavior under realistic decoupling conditions. For temperature-sensitive deployments, review the KDS datasheet's stability vs. temperature plot over the full Industrial envelope.

Frequently Asked Questions

Is the DSO221SY RoHS compliant?
Yes. The KDS DSO221SY is RoHS-compliant and lead-free, suitable for global deployment including EU and Asia markets.

What is the start-up time of the DSO221SY?
Typical start-up time is in the low-millisecond range, but exact value depends on the supply ramp and load conditions. Refer to the datasheet for measured values.

Does the DSO221SY need an external load capacitor?
No. The DSO221SY is a complete oscillator with internal load capacitors, so no external capacitor is required.
