AK8142

Overview

The AK8142 is a programmable clock generator IC manufactured by Asahi Kasei Microdevices. It integrates a Phase-Locked Loop (PLL) to generate precise clock signals from a single input frequency. The device operates within a supply voltage range of 3V to 3.6V and supports an input frequency of up to 24MHz. It is housed in a 16-TSSOP surface-mount package with a width of 4.40mm, designed for applications requiring stable clock generation in compact electronic systems.

Feature Summary

• Integrates a programmable PLL for flexible clock signal generation
• Supports high-frequency operation with a 24MHz input capability
• Utilizes a compact 16-pin TSSOP surface-mount package

Applications

• General-purpose clock generation in embedded systems
• Timing reference sources for digital circuits
• Clock distribution in consumer electronics

Procurement Notes

Verify the specific manufacturer designation, as documentation references both Asahi Kasei Microsystems and Asahi Kasei Microdevices. Confirm the package type matches the required 16-TSSOP form factor. Check lifecycle status, as some distributors list this component as obsolete. Ensure the operating voltage requirements align with the 3V to 3.6V specification before integration into the target design.

Selection Notes

Select this component when a dedicated programmable clock generator is required for timing-critical applications. The choice depends on the need for a single-chip PLL solution that accepts a 24MHz input. Consider the physical constraints of the 16-TSSOP package and the specific voltage tolerance of 3V to 3.6V during system architecture planning.

Part Context

The AK8142 belongs to the family of clock generator ICs produced by Asahi Kasei Microdevices. These components are designed to provide reliable timing solutions for various electronic devices. The company specializes in mixed-signal technologies, and this part represents their offering in the programmable clock generation segment, distinct from their sensor or audio product lines.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if sourcing alternatives due to the obsolete status noted by some distributors.
