The MAX5862 is an integrated, high-density, downstream cable QAM modulator, digital upconverter (DUC) and RF digital-to-analog converter (RF-DAC). The device performs QAM mapping, pulse shaping and digital RF upconversion of forward-error-correction (FEC) encoded data with full agility and drives a single RF-port using a 14-bit 4.6Gsps DAC. The device digitally synthesizes RF signals with up to 32 DOCSIS-compliant 6MHz QAM or 8MHz QAM channels. The device has fixed QAM capacity and provides high-density QAM modulation with very low power dissipation (4.2W at 32 QAMs) in a compact 12mm x 17mm footprint.
The device accepts FEC-encoded CMOS data (symbols) on a single 10-bit input port that accepts up to 32 time-interleaved digital data streams. Each channel features an individually configurable QAM mapper, RRC filter, and arbitrary rate resampler (ARR). The device performs pulse shaping, resampling, interpolation and quadrature modulation of input data, supporting all data rates defined in DOCSIS 3.0 and DVB-C. A cascade of interpolation filters, complex modulators, and channel combiners allow modulation of the signal to any frequency from 47MHz to 1006MHz. Integrated direct digital frequency synthesizers allow positioning of the QAM channels with a resolution of 125Hz. The interpolation filters and resamplers provide linear phase and excellent gain flatness. Output data from the last modulator is fed to a digital-predistortion (DPD) block that can be used to correct distortion in the device’s integrated RF-DAC and output amplifiers external to the device.
