STN93321/STN93240 are complete Total Spectrum Reception (TSR™ ) SOCs designed for cable gateways based on DOCSIS 3.1/DOCSIS 3.0 standards and coupled with Intel Puma7/Puma6 processors. They include downstream and upstream monitoring which is an important feature immensely helping operators remotely monitor field issues with lower overhead and cost.
The STN93321 has a unique patented architecture, TSR™, that grants the ability to digitize the entire band and consequently deliver up to 32 legacy cable channels and 2 OFDM cable channels at the same time. This is achieved due to the unsurpassed level of integration that includes a very high performance wide band RF front-end, a multi-GS/s high resolution Analog-to-Digital Convertor with a complex Digital Signal Processing Unit for cable reception.
The upstream path receives high speed data from PUMA 7 and generates up to 204MHz wide band upstream QAM signal using high resolution low spurious high speed Digital to Analog Converter.
