Dual, 16-bit, 12.6 GSPS RF DAC, with channelizers
AD9172 is a high performance, dual, 16-bit digital-to-analog converter (DAC) that supports DAC sample rates to 12.6 Gsamples/sec. The device features an 8-lane, 15 Gbps JESD204B data input port, a high performance, on-chip DAC clock multiplier, and digital signal processing capabilities targeted at single-band and multiband direct to radio frequency (RF) wireless applications.
The DAC 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. The device supports up to a 1.5 GSPS complex data rate per input channel and is capable of aggregating multiple complex input data streams up to a maximum complex data rate of 1.5 GSPS. It also supports ultrawide bandwidth modes bypassing the channelizers to provide maximum data rates of up to 3.08 GSPS (with 16-bit resolution) and 4.1 GSPS (with 12-bit resolution).
The device comes in a 144-ball BGA_ED package. There is an evaluation board (pictured, above), which is an FMC form-factor board with FMC connector that complies to the Vita 57.1 standard; it is intended to be used with a compatible FMC carrier board.
