Core Specifications

Best-Fit Applications

• USB and Ethernet reference clocks
• embedded MCU and peripheral timing
• Industrial wireless and timing-critical embedded designs
• USB and Ethernet reference clocks with strict frequency accuracy and stability

Selection Guidance

For USB and Ethernet reference clocks designs, confirm the DSO221SBM frequency stability and phase-noise profile against your receiver acquisition window. The 5.0 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

How does the DSO221SBM differ from other KDS SPXO parts?
The DSO221SBM uses the 2.5x2.0x0.9 SMD package with 3.3–52 MHz output. Compare against other package sizes and frequency points to find the best fit for your board layout.

Can the DSO221SBM be used as a direct replacement for similar parts?
In many cases yes. The 2.5x2.0x0.9 package and standard 4-pad layout support drop-in replacement across manufacturers. Verify pin-out and supply voltage before substitution.

What is the typical phase noise of the DSO221SBM?
Phase noise depends on the output frequency and offset. Refer to the KDS datasheet for the DSO221SBM time-domain and phase-noise plots at the frequencies of interest.
