Selection Guidance

For FPGA and DSP timing references designs, confirm the DS2520AS 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 Automotive envelope.

Frequently Asked Questions

Is the DS2520AS RoHS compliant?
Yes. The KDS DS2520AS is RoHS-compliant and lead-free, suitable for global deployment including EU and Asia markets.

What is the start-up time of the DS2520AS?
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 DS2520AS need an external load capacitor?
No. The DS2520AS is a complete oscillator with internal load capacitors, so no external capacitor is required.
