Selection Guidance

For high-speed serial interfaces and networking designs, confirm the DS2520AD frequency stability and phase-noise profile against your receiver acquisition window. The see datasheet supply envelope supports direct interface with common logic families, and the 2.5x2.0x1.0 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 Automotive envelope.

Frequently Asked Questions

Is the DS2520AD RoHS compliant?
Yes. The KDS DS2520AD is RoHS-compliant and lead-free, suitable for global deployment including EU and Asia markets.

What is the start-up time of the DS2520AD?
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 DS2520AD need an external load capacitor?
No. The DS2520AD is a complete oscillator with internal load capacitors, so no external capacitor is required.
