Core Specifications

Best-Fit Applications

• wireless modules and Bluetooth timing paths
• LTE and 5G NR synchronization
• Industrial wireless and timing-critical embedded designs
• wireless modules and Bluetooth timing paths with strict frequency accuracy and stability

Selection Guidance

For wireless modules and Bluetooth timing paths designs, confirm the DSB221SSB frequency stability and phase-noise profile against your receiver acquisition window. The 1.62–3.63 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 DSB221SSB RoHS compliant?
Yes. The KDS DSB221SSB is RoHS-compliant and lead-free, suitable for global deployment including EU and Asia markets.

What is the start-up time of the DSB221SSB?
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 DSB221SSB need an external load capacitor?
No. The DSB221SSB is a complete oscillator with internal load capacitors, so no external capacitor is required.
