Analog Devices MAX5861 | Demoboard MAX5861EVKIT

Description

The MAX5861 evaluation kit (EV kit) contains a MAX5861 high-density downstream cable SCQAM and OFDM modulator that integrates a digital up-converter (DUC) and a RF Digital to Analog Converter (RF-DAC). The MAX5861 DUC performs SCQAM and OFDM mapping, pulse shaping, and digital RF up-conversion with full agility and then drives a 14-bit 5Gsps RF-DAC. The device digitally synthesizes RF signals with up to 160 DOCSIS®-compliant 6MHz QAM channels (or up to 120 8MHz QAM channels) on a single RF port at frequencies from 47MHz to 1218MHz. The MAX5861 device provides up to 6 channels of OFDM IFFT processing. Each of the OFDM channels provide up to 192MHz of bandwidth, for a combined potential 1152MHz of modulation bandwidth. The MAX5861 can support up to six blocks powered on at the same time, where a block is defined as an OFDM channel or a 32-channel SCQAM block. The MAX5861 EV kit provides a complete system solution for high-density SCQAM and OFDM modulation targeting the DOCSIS 3.1 solution with very low power dissipation.
