The MxL231 is a low-power, upstream PGA IC that is designed for DOCSIS 3.0 applications with extended power capability. The MxL231 targets DOCSIS and EuroDOCSIS cable gateway designs.
The amplifier covers a frequency range of 5MHz to 85MHz, and can transmit eight simultaneous 64-QAM signals, each at 56dBmV at the balun output. The MxL231 is designed to be used in conjunction with all MaxLinear DOCSIS 3.0 Full-Spectrum Capture™ (FSC™) tuners, such as the MxL265D, MxL267D, and MxL268.
The MxL231 is configurable through an SPI bus and operates using a single 3.3V supply. The MxL231 is offered in a small 4mm x 4mm footprint, 24-pin QFN package.
