High-density QAM modulator chipset enables the next-generation connected home experience
The MAX5880/MAX5882 delivers up to 32 times more broadband cable capacity per RF port compared to a conventional analog upconverter, and saves up to 93% in power dissipation per QAM (quadrature amplitude modulation) channel. The QAM modulator chipset performance exceeds Cable Labs DOCSIS 3.0 RF specifications.
This highly integrated and scalable solution gives cable service providers the bandwidth for tomorrow’s cable services while reducing CAPEX and OPEX today. A single RF port enabled by the MAX5880/MAX5882 chipset replaces multiple QAM modulator boxes needed to deliver broadcast TV, high-speed data and VoIP triple-play services, as well as video-on-demand, switched digital video, and future interactive IPTV in the home.
The MAX5880 DUC interfaces seamlessly with the MAX5882, 14-bit 4.6Gsps RF DAC. The QAM modulator chipset synthesizes up to 128 QAM channels across the entire 50 MHz to 1 GHz downstream cable spectrum. Cable service providers can now deliver all their broadband content on a single RF port for an entire cable service group. The MAX5880 DUC is a scalable and software upgradeable solution that allows cable service providers to add future capacity without modifying existing hardware. The industry-leading MAX5882 RF DAC provides the conversion speed and dynamic performance necessary for wideband modulation that exceeds the stringent DOCSIS 3.0 RF requirements.
Availability
The MAX5880 DUC and MAX5882 RF DAC fit in two 17mm x 17mm packages.
A high-speed data-converter evaluation (EV) platform and EV kits are available to evaluate the MAX5880 DUC/MAX5882 RF DAC chipset. A reference design and development platform is also available.
The MAX5880/MAX5882 QAM modulator chipset is fully released and in production.
