Analog Devices Inc. AD9172 16-Bit Digital-to-Analog Converters

Analog Devices Inc. AD9172 16-Bit Digital-to-Analog Converters are high-performance converters that support DAC sample rates up to 12.6GSPS. The AD9172 features an 8-lane, 15Gbps JESD204B data input port, a high performance and on-chip DAC clock multiplier. The devices also feature digital signal processing capabilities targeted at single-band and multiband direct to radio frequency (RF) wireless applications. The AD9172 from Analog Devices features three complex data input channels per RF DAC that are bypassable. Each data input channel includes a configurable gain stage, an interpolation filter, and a channel numerically controlled oscillator (NCO) for flexible, multiband frequency planning.
