Core Specifications

Best-Fit Applications

• wireless baseband and RF modules
• high-speed data acquisition
• Industrial wireless and timing-critical embedded designs
• wireless baseband and RF modules with strict frequency accuracy and stability

Selection Guidance

For wireless baseband and RF modules designs, confirm the DSO321SR 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 3.2x2.5x1.2 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,Automotive envelope.

Frequently Asked Questions

Is the DSO321SR RoHS compliant?
Yes. The KDS DSO321SR is RoHS-compliant and lead-free, suitable for global deployment including EU and Asia markets.

What is the start-up time of the DSO321SR?
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 DSO321SR need an external load capacitor?
No. The DSO321SR is a complete oscillator with internal load capacitors, so no external capacitor is required.
