Part details & applications

The AD9173 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, 15.4 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 AD9173 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 1.54 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 1.54 GSPS. Additionally, the AD9173 supports ultrawide bandwidth modes bypassing the channelizers to provide maximum data rates of up to 3.08 GSPS (with 11-bit resolution using 16-bit serializer/deserializer (SERDES) packing) and 3.4 GSPS (with 11-bit resolution using 12-bit SERDES packing).

The AD9173 is available in a 144-ball BGA_ED package.

APPLICATIONS

Wireless communications infrastructure
- Multiband base station radios
