QAM Modulator Chipset fosters Next-Gen connectivity in homes.
Press Release Summary:
Comprised of MAX5880 digital upconverter and 14-bit, 4.6 GSPS MAX5882 RF DAC, high-density QAM (quadrature amplitude modulation) modulator chipset synthesizes up to 128 QAM channels across entire 50 MHz to 1 GHz downstream cable spectrum. This gives cable service providers bandwidth for future cable services while reducing CAPEX and OPEX. Performance exceeds Cable Labs® DOCSIS® 3.0 RF specifications, and single RF port enabled by chipset replaces multiple QAM modulator boxes.
Original Press Release:
Maxim's High-Density QAM Modulator Chipset Enables the Next-Generation Connected Home Experience
Maxim's scalable QAM modulator chipset delivers next-generation triple-play services, increases Edge-QAM/CMTS capacity, and reduces cable service provider CAPEX and OPEX
Sunnyvale, CA-Maxim Integrated Products, Inc. (NASDAQ: MXIM) announces a new high-density, wideband, scalable QAM modulator chipset: the MAX5880 digital upconverter (DUC) and MAX5882 RF digital-to-analog converter (RF DAC).
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 50MHz to 1GHz 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.
Consumers' bandwidth demand drives QAM channel and RF port growth
One thing is certain, each physical RF port, whether on a CMTS or edge QAM, is going to support exponentially more QAM channels than current generation platforms. This evolution is going to keep port demand among MSOs high for at least the next five years"
