Analog Devices / Maxim Integrated MAX5861 High-Density Downstream Cable Modulator
Analog Devices MAX5861 High-Density Downstream Cable Modulator is optimized for converged cable access platform (CCAP) hardware. MAX5861 performs baseband I/Q symbols to RF upconversion to digitally synthesize a selectable combination of Single-Carrier Quadrature Amplitude Modulation (SCQ-AM) and orthogonal frequency-division multiplexing (OFDM) blocks on a single radio frequency port. Analog Devices MAX5861 High-Density Downstream Cable Modulator SCQAM input port A accepts 10-bit Forward Error Correction (FEC)-encoded data for up to 160 (6MHz) individually programmable channels.
