TDA7708LX32

RF Receivers Overview

The TDA7708LX32 is a single-chip fully-CMOS AM/FM tuner designed for terrestrial radio broadcasting receivers. It operates at a supply voltage of 3.3 V, with a maximum of 3.45 V and minimum of 3.15 V. The device draws an operating supply current of 350 mA and functions within a temperature range of -40°C to +85°C. It is housed in a 64-VFQFPN package measuring 9 mm x 9 mm x 1 mm. The component is AEC-Q100 qualified and utilizes submicron silicon technology.

RF Receivers Feature Summary

• Integrates multiple front-end low-noise amplifiers covering AM LW/MW/SW bands and the entire FM band with advanced automatic gain control stages.
• Digitizes signals using a high dynamic range ADC and processes complex phase-quadrature baseband signals for multipath noise mitigation.
• Features integrated RDS decoding and HD-Radio channel filtering capabilities.
• Requires minimal external components due to cutting-edge circuit techniques that address challenges in zero IF receiver designs.

RF Receivers Applications

• Automotive grade receivers
• Car radios
• Radio devices requiring high performance and reliability

RF Receivers Procurement Notes

Verify the specific suffix (LX32) against the manufacturer's official documentation to confirm pinout and packaging details. Ensure compatibility with the intended microcontroller for firmware booting, as the IC requires a small code download. Confirm AEC-Q100 qualification status if automotive grade compliance is mandatory for the final assembly.

RF Receivers Selection Notes

Select this component for applications demanding low external component count and high integration levels. It is suitable for systems where limited microcontroller code storage exists, given the small firmware requirement. Consider pairing with the STA680 co-processor for complete HD-Radio solutions or the STA660DRM for DRM reception.

RF Receivers Part Context

The TDA7708LX32 belongs to the TDA7708 family of AM/FM/HD-Radio submicron technology automotive receivers. This series combines state-of-the-art performance with cost-effective implementation. The LX32 variant specifically denotes the packaging configuration within the broader product line aimed at challenging quality and reliability requirements.

RF Receivers Replacement Considerations

The TDA7708LX64TR is a related variant within the same family, sharing identical electrical specifications and functionality but differing in factory packaging quantity. Verify package compatibility before substitution.
