Full Spectrum Capture Satellite Digital ODU IC, 5 Input
Product Brief


The MxL865 is a low-power, single-chip Full- Spectrum Capture™ (FSC™) satellite digital ODU IC that features five wide band inputs for LNBF applications. The MxL865, with an external splitter, can be used in MDU applications as well. In both configurations, the MxL865 supports up to 32 stacked output channels in a static configuration, and up to 24 stacked output channels in a dynamic configuration.
The MxL865 integrates a host CPU microcontroller, FSK, and DiSEqC modems, and power management controllers. In each configuration, the MxL865 supports 950MHz– 2150MHz IF output with flexible channel grid and bandwidth configurations.
All major supporting analog functions are incorporated into the MxL865, such as broadband input and output filters, RF gain blocks, channel filters, PLLs, and AGC functionality. With its high level of integration and low power consumption, the MxL865 enables a true single-chip satellite ODU solution for modern LNBs and MDU switches that require compact board design and low cost.
The MxL865 uses 1.8V and 1.1V dual supplies. The MxL865 is available in a small 10mm x 10mm footprint, 88-pin QFN package.
