The AD9172 is a high performance, dual, 16-bit digital-to-analog converter (DAC) that supports DAC sample rates to 12.6 GSPS. 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 AD9172 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. Additionally, the AD9172 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 AD9172 is available in a 144-ball BGA_ED package.
**Product Highlights**
1. Supports single-band and multiband wireless applications with three bypassable complex data input channels per RF DAC at a maximum complex input data rate of 1.5 GSPS. One independent NCO per input channel.
2. Ultrawide bandwidth channel bypass modes supporting up to 3 GSPS data rates with 16-bit resolution and 4 GSPS with 12-bit resolution.
3. Low power dual converter decreases the amount of power consumption needed in high bandwidth and multichannel applications.
