描述 Description

The MxL265D is a cable gateway front-end SoC that supports 16 downstream channels and 8 upstream channels (16 x 8). The MxL265D targets DOCSIS and Euro-DOCSIS cable gateway designs.

The MxL265D IC captures the full, 1GHz cable bandwidth, and is capable of providing up to 16 channels of digitized I/Q data through a SerDes interface, and has a maximum serial baud rate of 5.4Gbps. The MxL265D 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 MxL265D enables high-speed broadband data solutions with a compact board design and low BOM cost. The MxL265D IC is controlled through an I2C interface and operates using 3.3V, 1.8V, and 1.1V supplies. The MxL265D is available in a small 7mm x 7mm footprint 48-pin QFN package.
