ISL9492ERZ - Renesas Electronics

Description: The ISL9492 is a highly integrated voltage regulator and interface IC specifically designed for supplying power and control signals from advanced satellite set-top box (STB) modules to the low noise blocks (LNB) of a single antenna port. It also supports DiSEqC tone generation and modulation with diagnostic status read-back. Controlling the ISL9492 is simple via the I2C bus by writing 8 bit words onto the System Registers (SR). The device design makes the total LNB supply design simple, efficient and compac
