Product Details

The AD9177 is a highly integrated device with four 16-bit, 12 GSPS maximum sample rate, RF digital-to-analog converter (DAC) cores supporting up to eight baseband channels. The device is well suited for applications requiring wideband DACs to process signals of wide instantaneous bandwidth. The device features an 8-lane, 24.75 Gbps JESD204C or 15.5 Gbps JESD204B data receiver (JRx) port, an on-chip clock multiplier, and digital signal processing (DSP) datapaths capable of processing complex signals for wide-band or multiband direct to RF applications, phase array radar systems, and electronic warfare applications. The DSP datapaths can be bypassed to allow a direct connection between the data receiver port and the DAC cores.

For direct digital synthesis (DDS) applications, the AD9177 can be operated without a data receiver port to generate multiple sine wave tones of varying frequencies. The main numerically controlled oscillator (NCO) block inside each of the four course digital upconverters (DUCs) contains one 48-bit NCO and a bank of thirty one 32-bit NCOs, each with an independent phase accumulator. Similarly, the main NCO block inside each of the course and fine digital downconverters (DDCs) in the receive datapath contains a bank of sixteen 48-bit NCOs that can be looped into the transmit datapath for processing ahead of the course DUCs and DAC outputs. Combined with general-purpose input/output (GPIO) controls for frequency hopping, preconfigurable profile selection, and the ability to synchronize the NCOs to a common trigger using the SYSREF input port, this bank allows phase coherent fast frequency hopping (FFH) for applications where multiple devices are synchronized or where NCO frequencies are continuously adjusted during operation.

APPLICATIONS

  • Wireless communications infrastructure
  • Microwave point-to-point, E-band, and 5G mm wave
  • Broadband communications systems
  • DOCSIS 3.1 and 4.0 CMTS
  • Phased array radar and electronic warfare
  • Electronic test and measurement systems

Design Tools

MxFE JESD204 Mode Selector Tool

The JESD204B/C Mode Selector Tool is a simple command line-based Windows executable that can be used to narrow down the number of JESD204x modes to only include those modes that support the user’s specific application use case. The tool guides the user through a use case description flow chart and gives the user a small list of applicable transmit and/or receive modes to choose from. This tool is applicable to the AD9081, AD9082, AD9177, AD9207, AD9209, AD9986, and AD9988.

JESD204x Frame Mapping Table Generator

The JESD204x Frame Mapping Table Generator tool consists of two Windows executables that will allow the user to input any valid combination of JESD204x parameters (L, M, F, S, NP) in order to output a .csv file that illustrates the frame mapping of the JESD204x mode in table format. There is an executable that allows the user to input a single JESD204x mode and another, that allows the user to input the parameters for multiple JESD204x modes in a specified .csv format in order to output a .csv file that illustrates the frame mapping of each of the JESD204x modes that were input into separate tables.
