Description
The ZXNB4204 is a single chip power management and control solution for LNB's. The highly integrated solution provides all the required FET and mixer bias, control detection and decoding and a stable power supply for the IF amplifier and additional support functions. Packaged in a small 16 pin package the ZXNB only requires 3 external components providing a very small compact solution. Being at the heart of the LNB monitoring the control, power management and environmental conditions, the ZXNB4204 is able to provide reliable solution eliminating effects such as false switching and over loading.
