Analog Devices Inc. (ADI), a global leader in high-performance signal processing technology and the data converter market share leader*, introduced two RF (radio frequency) D/A converters that are able to synthesize the entire downstream (transmit) cable spectrum from a single RF port. Supporting data rates up to 2.8 GSPS, the single-channel, 14-bit AD9129 and 11-bit AD9119 RF D/A converters allow cable operators to reduce the total system power and component count of CATV (CMTS) infrastructure equipment, simplify system design, and lower total bill of material costs.
