製品概要

The AD9174 is a high performance, dual, 16-bit digital-to-analog converter (DAC) that supports DAC sample rates up 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 AD9174 features three complex data input channels per RF DAC datapath. Each input channel is fully bypassable. Each data input channel (or channelizer) includes a configurable gain stage, an interpolation filter, and a channel numerically controlled oscillator (NCO) for flexible, multiband frequency planning. The AD9174 supports an input data rate of up to a 3.08 GSPS complex (inphase/quadrature (I/Q)), or up to 6.16 GSPS non-complex (real), and is capable of allocating multiple complex input data streams to the assigned channels for individual processing. Each group of three channelizers is summed into a respective main datapath for additional processing when needed. Each main datapath includes an interpolation filter and one 48-bit main NCO ahead of the RF DAC core. Using the modulator switch, the outputs of a main datapath can be either routed to DAC0 alone for operating as a single DAC, or routed to both DAC0 and DAC1 for operating as a dual, intermediate frequency DAC (IF DAC).

The AD9174 also supports ultrawide data rate modes that allow bypassing the channelizers and main datapaths to provide maximum data rates of up to 6.16 GSPS as a single, 16-bit DAC, up to 3.08 GSPS as a dual, 16-bit DAC, or up to 4.1 GSPS as a dual, 12-bit DAC.

Additionally, the main NCO blocks in the AD9174 contain a bank of 31, 32-bit NCOs, each with an independent phase accumulator. Combined with a 80 MHz serial peripheral interface (SPI) for programming the NCOs, this bank allows a phase coherent, fast frequency hopping (FFH) for applications where the NCO frequencies are continuously adjusted during operation.

The AD9174 is available in a 144-ball BGA_ED package.
