The MxL268 is a cable gateway front-end SoC that supports 32 downstream channels and 8 upstream channels (32 x 8). The MxL268 targets DOCSIS and Euro-DOCSIS cable gateway designs.
The MxL268 IC captures the full, 1GHz cable bandwidth, and is capable of providing 24 channels of digitized I/Q data and 8 channels of demodulated data over SerDes. The MxL268 IC also receives digitized upstream signals from a DOCSIS back-end IC using the SerDes interface, and outputs upstream analog signals in the 5MHz to 85MHz range to an external PGA.
With its high integration and low-power consumption, the MxL268 enables high-speed broadband data solutions with a compact board design and low BOM cost. The MxL268 IC is controlled through an I2C interface and operates using 3.3V, 1.8V, and 1.1V supplies. The MxL268 is available in a small 7mm x 7mm footprint 48-pin QFN package.
