AK1541

Overview

The AK1541 is a highly integrated RF frequency synthesizer manufactured by Asahi Kasei Microdevices. It operates within a frequency range of 20 to 600MHz and utilizes an advanced fractional-N Delta-Sigma architecture for precise signal generation. The device is packaged in a compact 24-QFN (4x4mm) surface-mount configuration with an exposed pad, designed for efficient thermal management and space-constrained applications.

Feature Summary

• Utilizes advanced fractional-N Delta-Sigma architecture for high-performance frequency synthesis
• Provides integrated PLL RF frequency generation capabilities
• Features a compact 24-QFN package design for space-efficient integration

Applications

• RF communication systems requiring stable frequency sources
• Wireless infrastructure equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific ordering suffix against official documentation to ensure correct package variant and temperature grade. Confirm that the 24-QFN footprint matches the target PCB layout dimensions. Check for RoHS compliance status if required by project specifications. Ensure supply chain authenticity through authorized channels to avoid counterfeit components.

Selection Notes

Select this component when a wide tuning range up to 600MHz is required in a small form factor. The Delta-Sigma architecture offers advantages in phase noise performance compared to integer-N designs. Consider the exposed pad requirement for proper thermal dissipation during selection and board design.
