Product Overview: TEA5767CE from NXP
The TEA5767CE is a cutting-edge integrated circuit from NXP Semiconductors, designed specifically for portable radio applications. This high-performance, low-power FM stereo radio module operates in the frequency range of 76 - 108 MHz, which includes both the Japanese band and the standard FM broadcast band, making it a versatile choice for global FM radio applications.
One of the key features of the TEA5767CE is its fully integrated on-chip frequency synthesizer. This synthesizer requires no external components, which simplifies the design process and reduces the overall bill of materials for product development. Additionally, the TEA5767CE includes a programmable de-emphasis function (50/75 μs), automatic frequency control (AFC), and automatic gain control (AGC), ensuring high-quality audio performance and reliable operation across various signal conditions.
The device offers a search tuning function, which allows for easy station discovery, and can be controlled via a simple two-wire (I²C-bus) serial interface, making it convenient for interfacing with microcontrollers and other digital systems. The TEA5767CE also features a mute function, which can be activated or deactivated through software commands.
For energy-conscious designs, the TEA5767CE excels with its low-voltage operation, ranging from 2.5V to 5.5V, and its minimal power consumption. This makes it an ideal choice for battery-operated devices such as portable radios, clock radios, and mini-component systems.
Furthermore, the TEA5767CE comes in a compact SOT-37 package, allowing for space-efficient designs in small form-factor applications. Its lead-free construction and compliance with RoHS directives make it an environmentally friendly option that meets modern regulatory requirements.
In summary, the TEA5767CE from NXP is a feature-rich, high-performance FM radio module that offers ease of integration, low power consumption, and excellent radio performance, making it an outstanding choice for designers and manufacturers of portable audio devices worldwide.
