ISL9492ERZ-T
Single Output LNB Supply and Control Voltage Regulator with I2C Interface for Satellite Set-Top Box Designs
线性稳压器 SING OUTPUT LNB SUPP VAGEG FOR SATELLITE
The ISL9492ERZ-T 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).
