Product details
Overview
STA710ECTR from STMicroelectronics is an AEC-Q100 qualified, quad-band (AM/FM/WX, Band-III, Band-L), dual-channel automotive RF tuner IC for Software-Defined Radio systems. It integrates LNAs, on-chip IF filtering, a high-dynamic-range ΣΔ ADC, and configurable digital baseband interface (I2S or JESD204B), enabling reception of analog AM/FM/WX and digital standards DAB/DRM/HD-Radio™ in vehicle infotainment head units.
For engineers reviewing the STA710ECTR datasheet, STA710ECTR pinout, STA710ECTR application, or STA710ECTR equivalent, key selection considerations include its dual-channel architecture for FM phase-diversity and DAB/DRM MRC, 3.3 V supply operation, −40 °C to +85 °C ambient range, 483–504 mA supply current, and VFQFPN64 (9 × 9 × 1.0 mm) RoHS-compliant package.
Technical Context
The STA710ECTR implements a full CMOS RFCMOS front-end with two independent RF signal paths-each supporting simultaneous AM/FM/WX and DAB/DRM band reception-and integrates a PLL-based frequency synthesizer with 36.864 MHz crystal oscillator reference. Its ΣΔ ADC delivers >100 dB SNR before complex quadrature down-conversion.
Digital baseband output is delivered via software-selectable I2S (single-ended or LVDS) or JESD204B interfaces, supporting flexible integration with application processors. The internal RF switch matrix enables band switching without external PIN diodes or varicaps, reducing BOM count and board area.
Key Specifications

| Software-configurable digital interface | Single hardware design supports I2S or JESD204B via register programming-simplifies platform reuse across infotainment tiers. |
| High-dynamic-range ΣΔ ADC | Provides >100 dB SNR before baseband down-conversion-critical for decoding low-SNR DAB/DRM signals in moving vehicles. |
| AEC-Q100 Grade 3 qualification | Validated for −40 °C to +85 °C operation with 1000-cycle temperature cycling and 1000-hr HTOL-ensures reliability in automotive under-hood/head-unit environments. |
Applications
| Automotive Infotainment Head Unit | Digital Radio Receiver Module |
|---|---|
Use Scenario: Integrated into OEM vehicle head units for AM/FM/WX, HD-Radio™, DAB, and DRM broadcast reception. IC Role / Device Role / Timing Role: Front-end RF tuner providing digitized baseband I/Q data to application processor for demodulation and audio rendering.

IC Role / Device Role / Timing Role: Single-chip tuner with embedded ΣΔ ADC and programmable interface-replaces discrete tuner + ADC + interface logic. Use Value: Eliminates 12+ external passive components (e.g., bandpass filters, matching networks), reducing module size by ~40% and assembly cost. |
| HD-Radio™ Hybrid Digital Audio System | DRM Shortwave Broadcast Receiver |
Use Scenario: HD-Radio™ receiver in North American automotive or portable applications requiring analog/digital simulcast decoding. IC Role / Device Role / Timing Role: Provides synchronized dual-channel sampling for hybrid analog/digital signal separation and error-resilient decoding. Use Value: High dynamic range ADC preserves weak HD subcarriers during co-channel interference-enabling reliable digital audio even under marginal analog signal conditions. | Use Scenario: Portable or fixed-site DRM receiver for international shortwave broadcasting in remote or low-infrastructure regions. IC Role / Device Role / Timing Role: Tuner covering LW/MW/SW AM bands plus DRM-compatible Band-III/L-supports global shortwave coverage in one device.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive digital radio tuner applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si2151-A30-GM (Skyworks) | Single-channel tuner; supports DAB/DMB but not HD-Radio™; uses proprietary digital interface, not JESD204B. | Limited to DAB-only systems; lacks dual-channel diversity capability for FM/HD-Radio™. | Select only if DAB-only functionality suffices and host processor lacks JESD204B support. |
| MAX2175ETJ+ (Maxim) | Single-channel, wideband tuner (100 kHz–2.5 GHz); no integrated ΣΔ ADC-requires external ADC and interface logic. | Requires additional signal chain components; higher BOM count and layout complexity than STA710ECTR's integrated solution. | Choose only for non-automotive applications needing ultra-wideband coverage beyond broadcast bands. |
Compared with Si2151-A30-GM and MAX2175ETJ+, STA710ECTR uniquely combines dual-channel reception, integrated ΣΔ ADC, JESD204B/I2S flexibility, and AEC-Q100 qualification-making it the only drop-in solution for automotive HD-Radio™/DAB hybrid systems requiring multipath resilience and minimal external components.

FAQ
What digital interface modes does STA710ECTR support, and how are they selected?
STA710ECTR supports I2S (single-ended or LVDS) and JESD204B through software configuration via its I²C/SPI control interface. Mode selection is performed by writing to dedicated registers (e.g., REG_IFACE_CFG) after power-up and clock stabilization. No hardware strapping pins are required-interface behavior is fully programmable in-system.
Does STA710ECTR require external RF filtering components for AM/FM/DAB bands?
No. STA710ECTR integrates band-select filters and an RF switch matrix internally. External components are limited to DC-blocking capacitors and simple matching networks at each RF input (AM_IN, FM1_IN, etc.). No external PIN diodes, transformers, or varicap diodes are needed-verified per DB3858 Figure 5 and Table 6.
How is thermal management handled in the VFQFPN64 package?
The VFQFPN64 package features an exposed thermal pad soldered directly to the PCB ground plane. With a junction-to-ambient thermal resistance of 22 °C/W on thermally optimized 2s2p boards, the device dissipates up to 1.5 W. ST recommends minimum 4×4 mm² copper pour under the pad with ≥4 thermal vias (0.3 mm diameter) to meet Tj ≤ 125 °C at +85 °C ambient.
Can STA710ECTR receive HD-Radio™ and DAB simultaneously?
Yes-its dual-channel architecture allows concurrent HD-Radio™ (FM hybrid) and DAB reception. One channel processes the FM analog carrier and HD subcarriers, while the other handles DAB Band-III signals. Baseband data is time-aligned and delivered separately via the digital interface, enabling real-time comparison and seamless audio handover.
