STEVAL-LNBH05 Evaluation Board from STMicroelectronics

The STEVAL-LNBH05, brought to you by STMicroelectronics, is a state-of-the-art evaluation board designed for advanced satellite TV systems. This evaluation board is centered around the LNBH25L, a high-performance low-noise block converter (LNB) regulator IC, which is tailored for single-tuner satellite set-top boxes and home gateways. The LNBH25L is capable of providing the necessary voltages and signals for down-converting the high-frequency satellite signals to a lower frequency band that is suitable for demodulation and decoding.

Equipped with the latest technology, the STEVAL-LNBH05 offers multiple features that make it a robust and versatile tool for developers and engineers. The evaluation board supports DiSEqC 2.x communication protocol, allowing for bi-directional communication between the satellite receiver and dish. This enables users to control advanced satellite dish features such as remote signal switching, satellite selection, and more.

The board's built-in I2C interface facilitates easy programming and control, while the LNBH25L's integrated step-up and step-down converter ensures efficient power management, delivering the required 13/18V to the LNB with a low-noise figure and minimal power dissipation. The device's current protection feature and thermal shutdown ensure safe operation under varying conditions.

Designed with flexibility in mind, the STEVAL-LNBH05 is compatible with a wide range of supply voltages, from 8V to 15V, making it suitable for various applications and system configurations. Its compact form factor and comprehensive documentation allow for quick integration into existing setups or for use in the development of new satellite receiver systems.

Whether you are a professional working on the next generation of satellite receivers or an enthusiast experimenting with satellite signal processing, the STEVAL-LNBH05 evaluation board from STMicroelectronics provides the functionality and reliability needed to achieve your goals.
