TDA7515

RF Receivers Overview

The TDA7515 is an RF front-end receiver designed for AM/FM-DSP car radios with IF sampling. It integrates a high-performance tuner circuit featuring 10.7MHz IF sampling and RF AGC generation. The component supports AM and FM modulation formats with a specified frequency resolution of 3.6kHz. It operates on a supply voltage range of 7.5V to 10V and draws a receive current of 60mA. The device is housed in a 64-TQFP surface-mount package measuring 10x10mm. It is rated for automotive-grade operation within a temperature range of -40°C to 85°C.

RF Receivers Feature Summary

• Integrates high-performance tuner circuitry with 10.7MHz IF sampling capability for digital signal processing architectures
• Includes built-in RF automatic gain control (AGC) generation for optimized signal reception
• Supports both AM and FM modulation protocols within a single integrated front-end solution

RF Receivers Applications

• AM/FM-DSP car radio systems
• Automotive audio receiver front-ends
• IF sampling tuner circuits

RF Receivers Procurement Notes

Verify the specific suffix (e.g., TR) against the required packaging format, as standard listings may indicate tube packaging while tape-and-reel variants exist. Confirm that the 64-TQFP package dimensions align with the target PCB footprint. Ensure the design accommodates the 7.5V to 10V supply requirement and the 60mA current draw during active reception states. Check for end-of-life status implications regarding long-term availability and substitute sourcing strategies.

RF Receivers Selection Notes

Select this component when designing AM/FM receivers that utilize digital signal processing with direct IF sampling at 10.7MHz. It is suitable for applications requiring integrated RF AGC and compact surface-mount integration in automotive environments. Consider alternative models if the system requires different IF frequencies or non-sampling architectures. Verify compatibility with the host DSP interface requirements before finalizing the bill of materials.

RF Receivers Part Context

The TDA7515 belongs to STMicroelectronics' portfolio of automotive RF front-end solutions. It is part of a family that includes related models such as the TDA7529 and TDA7528, which also support IF sampling for DSP-based car radios. These components are engineered to reduce external component count while maintaining high performance in demanding automotive electromagnetic environments.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers include TDA7529 and TDA7528 from STMicroelectronics, which share similar IF sampling capabilities for AM/FM DSP car radios.
