MAX5862DUXH+ General Description

The MAX5862 is an integrated, high-density, downstreamcable QAM modulator, digital upconverter (DUC) andRF digital-to-analog converter (RF-DAC). The deviceperforms QAM mapping, pulse shaping and digital RFupconversion of forward-error-correction (FEC) encodeddata with full agility and drives a single RF-port using a14-bit 4.6Gsps DAC. The device digitally synthesizes RFsignals with up to 32 DOCSIS-compliant 6MHz QAM or8MHz QAM channels. The device has fixed QAM capacityand provides high-density QAM modulation with very lowpower dissipation (4.2W at 32 QAMs) in a compact 12mmx 17mm footprint.
