AK1547

Overview

The AK1547 is a clock generator integrated circuit manufactured by Asahi Kasei Microdevices (AKM). It operates at a frequency of 4 GHz and utilizes a Phase-Locked Loop (PLL) architecture. The device is housed in a 20-WFQFN package with an exposed pad. This component belongs to the Clock Generators and PLLs product category, designed for high-frequency signal generation applications.

Feature Summary

• Generates high-frequency clock signals up to 4 GHz
• Integrates Phase-Locked Loop (PLL) technology for stable frequency synthesis
• Utilizes a compact 20-WFQFN package with an exposed pad for thermal management

Applications

• High-speed digital system clock generation
• Communication equipment timing circuits
• Test and measurement instrument signal sources

Procurement Notes

Verify current availability status as the AK1547 is listed as no longer manufactured or obsolete in distributor records. Confirm compatibility with existing board layouts due to the specific 20-WFQFN package requirements. Check for end-of-life notifications from Asahi Kasei Microdevices before finalizing procurement plans.

Selection Notes

Select this component only if a 4 GHz output frequency and PLL-based clock generation are required. Ensure the design supports the 20-WFQFN package with an exposed pad for adequate thermal dissipation. Consider that the part may be discontinued; evaluate alternative solutions if long-term supply stability is critical for the project lifecycle.

Part Context

Asahi Kasei Microdevices (AKM) specializes in analog and mixed-signal semiconductor products, including sensors and audio ICs. The AK1547 represents their capability in high-frequency clock generation within the broader portfolio of timing and synchronization solutions used in advanced electronic systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the component being listed as no longer manufactured, engineers should consult official AKM resources or authorized distributors for potential obsolescence management strategies or approved cross-reference alternatives.
