ATR4253C-PVPW-76

Overview

The ATR4253C-PVPW-76 is an all-in-one integrated circuit designed for active FM antenna applications. Manufactured by Microchip Technology, this component functions as an RF IC antenna amplifier specifically tuned for the FM broadcast band ranging from 76MHz to 108MHz. It is housed in a compact 16-VQFN (3x3) surface-mount package with an exposed pad, facilitating efficient integration into portable electronic devices requiring FM reception capabilities.

Feature Summary

• Integrates antenna matching and amplification functions into a single compact IC
• Optimized for high-performance FM radio signal reception
• Designed for low-power consumption in mobile consumer electronics

Applications

• Portable FM radio receivers
• Smartphones and mobile communication devices
• In-car infotainment systems

Procurement Notes

Verify the specific ordering suffix '-76' against the official Microchip Technology datasheet to ensure compatibility with required tape-and-reel packaging specifications. Confirm that the 16-VQFN package dimensions align with the target PCB footprint design. Check product status documentation, as availability may be affected by end-of-life notifications or supply chain constraints associated with legacy components.

Selection Notes

Select this component when designing circuits requiring a unified solution for FM antenna impedance matching and signal amplification within strict space constraints. The 16-VQFN package is suitable for dense PCB layouts common in modern handheld devices. Ensure the operating voltage range matches the system power supply and verify thermal dissipation requirements for the exposed pad configuration during the layout phase.

Part Context

This part belongs to Microchip Technology's portfolio of RF and wireless integrated circuits, specifically targeting the FM antenna market segment. It represents a specialized solution for enhancing receiver sensitivity in compact form factors. The component is distinct from general-purpose amplifiers, focusing exclusively on the optimization of FM band performance through integrated passive and active elements.

Replacement Considerations

Consult Microchip Technology official documentation for confirmed substitute part numbers. Cross-reference pinout compatibility and electrical characteristics if considering alternative vendors. Verify that any replacement maintains the same 76MHz to 108MHz frequency coverage and package outline to ensure seamless integration without redesigning the surrounding circuitry.
