Voltage Regulators provide single LNB supply and control.
Generation 5 A8300 and A8300-1 are fully integrated linear and switching voltage regulators that provide power and interface signals to LNB down-converter via coaxial cable. While A8300 is optimized for low-profile ceramic boost capacitors, A8300-1 is designed for use with electrolytic capacitors. For DiSEqC™ communication, ICs provide internal 22 kHz tone gated with control pin or can accept...
