TDA7708CBTR

RF Receivers Overview

The TDA7708CBTR is a fully CMOS AM/FM tuner designed for terrestrial radio broadcasting receivers. It operates within a supply voltage range of 3.15V to 3.45V and supports modulation protocols including AM, FM, RDS, SW-LW, and HD-Radio. The device features a Low-IF architecture with digital IF processing and built-in IF-ADC for high dynamic range. It is housed in a 64-VFQFPN package (9x9mm) with a 0.5mm pitch. The component is qualified to AEC-Q100 standards for automotive applications and functions across an operating temperature range of -40°C to +85°C.

RF Receivers Procurement Notes

Verify the specific suffix 'CBTR' corresponds to the Tape and Reel packaging configuration as indicated by distributor data. Confirm that the 64-VFQFPN package dimensions match the target PCB footprint requirements. Ensure compatibility with the required I2C or SPI interface settings for system integration. Check for any recent Product Change Notifications regarding material or pinout modifications before finalizing procurement.

RF Receivers Selection Notes

Select this component when a single-chip solution for AM/FM/HD-Radio reception is required in automotive environments. It is suitable for designs prioritizing low external component count and small footprint. Consider the 64-pin VFQFPN package size for layout constraints. Verify that the system power supply aligns with the 3.15V to 3.45V operating range. This part is appropriate for applications requiring AEC-Q100 qualification and robust multipath performance.

RF Receivers Part Context

The TDA7708 series represents STMicroelectronics' submicron technology automotive receiver family. The CBTR variant specifically denotes the reel-packaged version of the 64-pin QFN device. It belongs to the broader TDA7708 product line which includes other package options like LX52. The series is designed to replace older discrete tuner solutions with a highly integrated CMOS approach.

RF Receivers Replacement Considerations

Direct substitutes include other TDA7708 variants such as TDA7708LX52, though package differences must be accounted for. Cross-reference with previous generation STMicroelectronics tuners if architectural changes are acceptable. Verify pin-to-pin compatibility if replacing legacy components from other manufacturers.
