Analog Devices Inc. AD917x 16-Bit Digital-to-Analog Converters

Analog Devices AD917x 16-Bit Digital-to-Analog Converters (DACs) are dual, high-performance converters that support DAC sample rates up to 12.6GSPS. The AD917x converters feature an 8-lane, 15Gbps JESD204B data input port and a high-performance, on-chip DAC clock multiplier. The devices also feature digital-signal processing capabilities targeted at single-band and multi-band direct to radio frequency (RF) wireless applications. Analog Devices AD917x DACs include 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.
