Selection Guidance

For automotive infotainment and telematics designs, confirm the DSA221SDN frequency stability and phase-noise profile against your receiver acquisition window. The 1.68–3.5 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 DSA221SDN RoHS compliant?
Yes. The KDS DSA221SDN is RoHS-compliant and lead-free, suitable for global deployment including EU and Asia markets.

What is the start-up time of the DSA221SDN?
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 DSA221SDN need an external load capacitor?
No. The DSA221SDN is a complete oscillator with internal load capacitors, so no external capacitor is required.
