Core Specifications

Best-Fit Applications

• consumer electronics and home appliances
• audio/video processing chains
• Industrial wireless and timing-critical embedded designs
• consumer electronics and home appliances with strict frequency accuracy and stability

Selection Guidance

For consumer electronics and home appliances designs, confirm the DSO221SHH 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 DSO221SHH RoHS compliant?
Yes. The KDS DSO221SHH is RoHS-compliant and lead-free, suitable for global deployment including EU and Asia markets.

What is the start-up time of the DSO221SHH?
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 DSO221SHH need an external load capacitor?
No. The DSO221SHH is a complete oscillator with internal load capacitors, so no external capacitor is required.
