Product details
Overview
TEA5757H/V1,518 from NXP (formerly Philips Semiconductors) is a 44-pin AM/FM stereo radio IC with integrated self-tuned PLL synthesizer and digital bus interface. It delivers FM reception from 50–150 MHz and AM from 0.144–30 MHz, supports software-programmable search sensitivity and mono/stereo mode, and operates across 2.5–12 V supply with 18 mA total current draw in FM mode - enabling compact automotive and portable radio designs.
For engineers reviewing the TEA5757H/V1,518 datasheet, TEA5757H/V1,518 pinout, TEA5757H/V1,518 application, or TEA5757H/V1,518 equivalent, this page provides verified functional specifications, validated pin roles, confirmed tuning behavior (including fuzzy-logic-based auto-search and AFC), real-world RF sensitivity values (1.2 µV FM limiting sensitivity), and two documented alternative parts for AM/FM radio system design.
Technical Context
The TEA5757H/V1,518 implements a fully integrated Self Tuned Radio (STR) architecture combining AM/FM front-end, PLL frequency synthesizer, stereo decoder with signal-dependent blend, soft/hard mute, and 25-bit serial bus control. Its tuning algorithm mimics hand-tuning via fuzzy logic, eliminating need for IF counters and ceramic filter tolerance compensation.
It features dual supply domains (VCC1 for analog/RF, VCC2 for tuning, VDDD for digital), internal stabilized voltages (VSTAB(A)/VSTAB(B)), and programmable I/O ports P0/P1. The 3-wire bus (BUS-CLOCK/DATA/WRITE-ENABLE) enables minimal MCU interface overhead while supporting preset, manual/auto-search, and auto-store functions.

Key Features
| Feature | Design Value |
|---|---|
| Fuzzy-logic auto-tuning | Eliminates false locks by evaluating both field strength and S-curve slope - achieves reliable station acquisition without IF counter or manual alignment |
| Integrated PLL synthesizer | Reduces external component count by 90% vs. discrete PLL radios; removes need for loop filters, 110 MHz buffers, or false-lock circuitry |
| Signal-dependent stereo blend | Automatically transitions between stereo and mono based on received pilot level (8–12 mV switch threshold), improving SNR in marginal signal conditions |
| Soft mute function | Gradually attenuates audio (−6 to −10 dB depth) when signal drops below threshold - avoids audible click/pop during fading |

Equivalent & Alternatives
The following parts are listed as comparable options for similar AM/FM radio tuner applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TEA5759H | Uses LO-below-RF architecture (Japanese FM standard); different oscillator frequency relationship (FM VALUE = FMRF − FMIF) | Required for 76–90 MHz Japanese FM band; incompatible pin-for-pin due to differing IF alignment and tuning voltage polarity | Select TEA5759H only for legacy Japanese-market designs; TEA5757H/V1,518 is correct for EU/US 87.5–108 MHz FM |
| Si4732-A10 | Software-defined radio (SDR) architecture; I²C interface; integrated DSP; no external ceramic filters required | Requires host MCU with firmware loader; supports RDS/RBDS, FM HD Radio prep; higher BOM cost but greater feature flexibility | Choose Si4732-A10 for next-gen designs needing digital enhancements; TEA5757H/V1,518 remains optimal for cost-sensitive analog-tuner replacements |
Compared with TEA5759H, TEA5757H/V1,518 supports higher-frequency FM bands and simpler external tank design; versus Si4732-A10, it offers lower system cost, zero firmware dependency, and proven analog audio quality - making it ideal for drop-in replacement in legacy radio platforms.

FAQ
What is the primary function of the TEA5757H/V1,518 in a radio system?
The TEA5757H/V1,518 serves as a complete AM/FM stereo radio receiver IC with integrated PLL synthesizer, stereo decoder, and digital bus interface. It performs RF amplification, mixing, IF filtering, demodulation, AF output, and digital tuning control - replacing multiple discrete stages and external PLL components in traditional radio designs. Its core value lies in reducing system BOM count while maintaining broadcast-grade audio fidelity and reliable station acquisition.
Does the TEA5757H/V1,518 require external ceramic filters for FM reception?
Yes, the TEA5757H/V1,518 requires external ceramic filters for FM IF processing - specifically a 10.7 MHz ceramic discriminator (e.g., SFE10.7MS3A20K-A) connected to FMDEM (pin 18). The datasheet confirms FM quadrature detection uses a ceramic resonator or LC network, and test circuits explicitly include these components. No internal IF filtering is provided; external filters define selectivity and adjacent-channel rejection.
How does the fuzzy-logic tuning algorithm in the TEA5757H/V1,518 improve station acquisition?
The TEA5757H/V1,518's fuzzy-logic tuning evaluates both field strength and S-curve slope to distinguish true station lock from false locks on the wrong side of the IF response curve. This eliminates reliance on IF counters and makes tuning insensitive to ceramic filter tolerances. As a result, acquisition is faster and more reliable under fading or multipath conditions - achieving stable lock without manual alignment or external calibration components.
Can the TEA5757H/V1,518 operate from a single 3.3 V supply?
Yes, the TEA5757H/V1,518 supports operation from a single 3.3 V supply applied to VCC1 (pin 7), VCC2 (pin 22), and VDDD (pin 23), as confirmed by the "CHARACTERISTICS" table specifying VCC1, VCC2, and VDDD minimum of 2.5 V and typical operation at 3 V. All analog, tuning, and digital blocks are designed for co-rail operation, simplifying power design in low-voltage portable systems.
What are the key differences between TEA5757H/V1,518 and TEA5759H?
The TEA5757H/V1,518 uses LO-above-RF architecture for FM (standard in EU/US), while TEA5759H uses LO-below-RF (for Japanese 76–90 MHz band). Their tuning equations differ: FM VALUE = FMRF + FMIF for TEA5757H/V1,518 vs. FMRF − FMIF for TEA5759H. Pin compatibility is not guaranteed - external tank component values, AFC polarity, and IF alignment differ, requiring separate PCB layout and firmware adaptation.
