Product Description
The MediaTek MT6140BN/D is a highly integrated system-on-chip (SoC) designed to provide advanced digital TV reception capabilities for mobile devices, portable TV receivers, and set-top boxes. One of the primary strengths of the MT6140BN/D is its wide support for multiple digital TV broadcast standards, making it an adaptable solution for devices used in various regions. It can handle DVB-T, DVB-T2, ISDB-T, and T-DMB signals, ensuring that users can enjoy digital TV in different parts of the world, from Europe to Latin America and Asia. This multi-standard support makes the MT6140BN/D ideal for mobile TV receivers that need to work across different broadcast systems without the need for separate chips.
At the heart of the MT6140BN/D’s performance is its highly sensitive RF tuner. The tuner covers a broad frequency range from 48 MHz to 1,000 MHz, which allows it to capture TV signals across the entire band for digital terrestrial TV and radio broadcasts. This wide frequency range makes the MT6140BN/D capable of receiving signals from various sources, including both DVB-T and ISDB-T transmissions, which operate on different frequency bands in different regions. The integrated Digital Signal Processor (DSP) within the chip handles the complex tasks of signal processing, including modulation, demodulation, error correction, and channel equalization. This ensures that even in areas with weak signals or interference, the MT6140BN/D can provide clear, stable TV reception.
The chip’s video and audio decoding capabilities make it suitable for high-quality multimedia applications. It can decode MPEG-2, MPEG-4, and H.264 video streams, supporting both HD and SD broadcasts. This allows the MT6140BN/D to be used in devices that require smooth video playback, such as mobile TVs, portable media players, or even in-car entertainment systems. The chip also supports AAC, HE-AAC, and MP3 audio formats, ensuring that users receive high-quality audio along with the video stream, delivering an immersive TV experience.
A key feature of the MT6140BN/D is its low power consumption, making it ideal for use in battery-powered, portable devices. The chip operates with a low voltage range of 1.2V to 1.8V, and it features dynamic power scaling to adjust its power usage based on the device's active or idle state. The chip’s standby mode further reduces power consumption when the device is not actively being used, which is critical for extending battery life in mobile devices. This power efficiency makes it well-suited for applications like mobile TV receivers, where longer battery life is a key concern for users.
The MT6140BN/D also offers a variety of interfaces for communication with other system components, such as I2C for configuration and control, SPI for high-speed data transfer, and USB 2.0 for external peripheral connections. These interfaces provide flexibility in integrating the chip into a wide range of products, from smartphones and tablets to standalone portable TV receivers.
In terms of physical integration, the MT6140BN/D comes in a compact QFN-40 package with a 6mm x 6mm footprint, making it suitable for space-constrained devices like mobile phones, tablets, and handheld TV receivers. Its small size and low power profile allow for easy integration into portable designs without taking up too much space or consuming excessive power.
Overall, the MediaTek MT6140BN/D is an excellent choice for applications that require digital TV reception, video and audio decoding, and efficient power management. Its support for multiple TV standards, high-performance signal processing, and low power consumption make it a versatile and reliable solution for mobile and portable entertainment devices.
