TDA7708SCB

RF Receivers Overview

The TDA7708SCB is a single-chip fully CMOS AM/FM tuner designed for terrestrial radio receivers. It operates at an operating supply voltage of 3.3 V, with a minimum operating temperature of -40 C and a maximum operating temperature of +85 C. The component is housed in a VFQFPN-52 package and holds AEC-Q100 qualification for automotive applications.

RF Receivers Feature Summary

• Features multiple front-end low-noise amplifiers (LNAs) covering AM LW/MW/SW bands and the entire FM band with advanced automatic gain control.
• Integrates on-chip intermediate frequency filtering and high dynamic range ADCs for complex phase accumulation baseband signal processing.
• Supports multipath noise suppression, integrated RDS decoding, and HD-Radio channel filtering capabilities.

RF Receivers Applications

• Automotive AM/FM radio receivers
• HD-Radio receiver solutions
• DRM receiver systems

RF Receivers Procurement Notes

Verify the specific suffix to confirm packaging configuration, as the SCB variant typically utilizes tray packaging while other variants may use tape and reel. Confirm that the procurement source provides official STMicroelectronics documentation to ensure the component meets AEC-Q100 automotive grade standards. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling procedures prior to assembly.

RF Receivers Selection Notes

Select this component for applications requiring minimal external components due to its advanced circuit implementation technology. It is suitable for systems where microcontroller code storage capacity is limited, as it requires very small firmware code to boot. Ensure the design supports the required digital audio output interfaces and I2C/I2S/SPI data interfaces for system integration.

RF Receivers Part Context

The TDA7708SCB belongs to the TDA7708S series of RF receivers. It is part of a family of automotive-grade CMOS tuners that integrate complete AM/FM reception with digital IF processing. This series is optimized for high performance and reliability in challenging automotive environments, often paired with external processors like the A680 for HD-Radio or A660 for DRM.

RF Receivers Replacement Considerations

The TDA7708LX52 serves as a functional alternative within the same product family, offering similar AM/FM reception capabilities but utilizing a 64-VFQFPN(9x9) package instead of the 52-pin configuration. Verify pin compatibility and firmware requirements when substituting between these variants.
