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 nu- merically controlled oscillator (NCO) for flexible, multiband frequen- cy 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/de- serializer (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. 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 1.54 GSPS with 11-bit resolution and 1.23 GSPS with 16-bit resolution. One independent NCO per input channel. 2. Ultrawide bandwidth channel bypass modes supporting up to 3.08 GSPS data rates with 11-bit resolution, 16-bit SERDES packing and 3.4 GSPS with 11-bit resolution, 12-bit SERDES packing. 3. Low power dual converter decreases the amount of power consumption needed in high bandwidth and multichannel appli- cations. |
