AK1573

Overview

The AK1573 is a frequency synthesizer integrated circuit manufactured by Asahi Kasei Microdevices. It is housed in a 24-lead Quad Flat No-leads (QFN) package with a 0.5 mm pitch, measuring 4 mm in length and 0.85 mm in maximum height. The device operates within an industrial temperature range of -40 °C to +85 °C. Electrical specifications include a supply voltage range of 2.7 V to 3.3 V, with a nominal voltage of 3 V. The maximum supply current is rated at 105 mA. The component utilizes a surface-mount technology suitable for automated assembly.

Feature Summary

• Integrated PLL frequency synthesizer functionality
• Compact 24-pin QFN package (HQCCN/LCC24,.16SQ,20)
• Industrial temperature rating (-40 °C to +85 °C)
• Low power consumption with max supply current of 105 mA

Applications

• Wireless communication systems requiring frequency synthesis
• RF front-end modules
• Consumer electronics with RF capabilities

Procurement Notes

Verify the specific suffix (e.g., AK1573B) against the manufacturer's official datasheet to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status and lead-free availability through authorized distributors. Check for any obsolescence notices or last-time buy notifications directly from Asahi Kasei Microdevices before finalizing procurement plans.

Selection Notes

Select this component when a compact, low-power frequency synthesizer is required for industrial applications. Ensure the design supports a 3V nominal supply and can accommodate the 105 mA peak current draw. Verify that the PCB layout allows for the thermal dissipation requirements of the exposed pad in the 24-QFN package.
