MaxLinear Inc. announced that Pro Brand International Inc. has selected the MxL865 Full-Spectrum Capture(TM) (FSC) system on chip (SoC) for a new direct broadcast satellite digital outdoor unit. The MxL865 is a digital channel-stacking SoC that supports up to 24 channels over a single cable for simplified connections between the indoor set-top boxes/gateways and rooftop LNBs and multi-dwelling unit switches. The device has five FSC inputs for a total capture bandwidth of 10 GHz and features a single L-band IF output.

PBI selected the MxL865 due to its high level of integration and low power consumption, which makes the deployment of high-density channel-stacking D-ODUs commercially viable for the first time. The 10mm x 10mm device integrates a host CPU microcontroller, FSK and DiSEqC modems, and power management controllers. All major analog functions are also integrated into the device, including broadband input and output filters, RF gain blocks, channel filters, PLLs and automatic gain control (AGC) circuitry.
