AK1573C

Overview

The AK1573C is a frequency synthesizer integrated circuit manufactured by Asahi Kasei Microdevices (AKM). It is housed in a 24-lead Quad Flat No-lead (QFN) package with dimensions of 4 mm length and 0.5 mm terminal pitch. 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.

Feature Summary

• Integrated PLL frequency synthesizer functionality
• 24-terminal QFN surface-mount package
• Industrial temperature rating (-40 °C to 85 °C)
• Low power consumption with 105 mA max supply current

Applications

• Frequency synthesis in communication systems
• Signal processing circuits requiring stable clock generation
• Embedded systems utilizing fractional-N PLL architectures

Procurement Notes

Verify the specific suffix 'C' against the official AKM datasheet to confirm pinout compatibility and electrical tolerances relative to other variants in the AK1573 series. Ensure the supplier provides documentation confirming the component meets the specified industrial temperature grade and RoHS compliance standards prior to integration.

Selection Notes

Select the AK1573C when a compact 24-pin form factor is required for frequency synthesis applications. Confirm that the system power budget accommodates the 105 mA maximum current draw. Verify that the operating environment remains within the -40 °C to 85 °C range to ensure reliable performance without derating.

Part Context

The AK1573C belongs to the AK1573 family of low-noise integrated VCOs and frequency synthesizers from Asahi Kasei Microsystems. This family includes related components such as the AK1572 and AK1574, which offer varying degrees of integration for down-conversion, up-conversion, and modulation tasks in wireless infrastructure.

Replacement Considerations

Direct substitutes may include the AK1572 or AK1574 if functional differences in mixer integration are acceptable. Cross-vendor alternatives like the ADF4153 require careful evaluation of pin compatibility and loop filter design adjustments.
