STA709TR

RF Receivers Overview

The STA709TR is a single-chip, full CMOS, quad-band front-end tuner designed for Software-Defined-Radio (SDR) systems. It supports AM, FM, HD Radio, and DAB standards with automotive-grade performance. The device operates on a supply voltage of 3.15V to 3.45V and draws a receive current of 309mA. It features I2C, I2S, and SPI data interfaces. The component is housed in a 64-VFQFPN (9x9) package with exposed pads, suitable for surface-mount installation. It functions within an operating temperature range of -40°C to 85°C.

RF Receivers Procurement Notes

Verify the specific ordering suffix 'TR' indicates reel packaging rather than bulk. Confirm AEC-Q100 qualification status matches project requirements. Ensure the 64-VFQFPN package dimensions align with PCB layout constraints. Check moisture sensitivity level (MSL 3) handling procedures during assembly. Validate that the 3.3V nominal supply voltage fits the system power budget.

RF Receivers Selection Notes

Select this component when a unified solution for AM, FM, HD Radio, and DAB reception is required in a compact form factor. The full CMOS technology allows for lower power consumption compared to hybrid solutions. Consider the digital output interface compatibility with the host processor before finalizing the choice. The automotive grade rating makes it suitable for harsh environmental conditions typical in vehicular applications.

RF Receivers Part Context

The STA709 series represents STMicroelectronics' advanced RF receiver lineup for automotive infotainment. It integrates quad-band tuning capabilities into a single package, reducing board space. The device complements other tuners like the STA710 and TDA7707 series by offering specialized SDR compatibility. Its design focuses on minimizing external passive components while maintaining high RF performance metrics.

RF Receivers Replacement Considerations

The STA710 is a related active part in the same family. Verify pinout and software compatibility if substituting between these models. No direct public substitute part numbers are confirmed in the provided documentation.
