KDS DS2520AK SPXO MHz 100–156.3 MHz 2.5x2.0x1.0 Crystal Oscillator

KDS DS2520AK SPXO MHz 100–156.3 MHz 2.5x2.0x1.0 Crystal Oscillator

The DS2520AK is a KDS simple-packaged crystal oscillator (SPXO) covering 100–156.3 MHz in a 2.5x2.0x1.0 SMD package. With see datasheet supply and Automotive temperature range, it serves USB and HDMI reference clocks and industrial controllers and embedded MCUs reference needs without the overhead of TCXO compensation.

Why Choose This Rating

• Low start-up time and stable oscillation across input voltage ramp
• Tight supply-pushing and load-pulling for predictable frequency behavior
• SPXO design without the overhead of TCXO compensation
• Reflow-solder-compatible SMD package for high-volume manufacturing
• see datasheet supply envelope compatible with mainstream 1.8V/2.5V/3.3V rails
• Industry-standard 2.5x2.0x1.0 footprint for drop-in replacement across designs

Core Specifications

Best-Fit Applications

• USB and HDMI reference clocks
• industrial controllers and embedded MCUs
• Industrial wireless and timing-critical embedded designs
• USB and HDMI reference clocks with strict frequency accuracy and stability

Selection Guidance

For USB and HDMI reference clocks designs, confirm the DS2520AK 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 DS2520AK RoHS compliant?
Yes. The KDS DS2520AK is RoHS-compliant and lead-free, suitable for global deployment including EU and Asia markets.

What is the start-up time of the DS2520AK?
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 DS2520AK need an external load capacitor?
No. The DS2520AK is a complete oscillator with internal load capacitors, so no external capacitor is required.
