MaxLinear Inc. and MStar Semiconductor announced a joint reference design that allows Chinese cable operators to deploy the next generation of ultra-high definition (UHD) smart cable gateway set-top boxes (STB). The MStar gateway platform uses MaxLinear’s MxL254C Full-Spectrum CaptureTM (FSC™) cable receiver IC, which digitizes the entire cable spectrum, performs the digital tuning and demodulation of up to four cable channels reducing power consumption, complexity and cost. The MxL254C also includes a parallel transport interface to the MPEG system-on-chip (SoC) providing an additional option for the serial transport interface. The smart gateway STB reference design enables cable operators in China, using MaxLinear’s leading FSC technology, to develop STBs with competitive features such as fast channel change, multi-screen share and remote network monitoring. The reference platform combines MaxLinear’s MxL254C cable receiver with MStar’s 4K MSA6Z18 SoC to offer cable operators the best-in-class UHD smart STB solution in a power and cost-optimized design. MSA6Z18 is a highly integrated, high performance UHD SoC fulfilling various CA/DRM requirement for STB application. With built-in high performance CPU, 3D GPU, VP9/HEVC decoder/encoder and full coverage of HDR technology, it provides the best complete solution for a rich features gateway. The MxL254 device is available for sampling and is in mass production.
