11-Bit, 5.6 GSPS, RF Digital-to-Analog Converter

Manufactured by:

Product Details

The AD9119/AD9129 are high performance, 11-/14-bit RF digital-to-analog - converters (DACs) supporting data rates up to 2.8 GSPS. The DAC core is based on a quad-switch architecture that enables dual-edge clocking operation, effectively increasing the DAC update rate to 5.6 GSPS when configured for Mix-Mode™ or 2× interpolation. The high dynamic range and bandwidth enable multicarrier generation up to 4.2 GHz.

In baseband mode, wide bandwidth capability combines with high dynamic range to support from 1 to 158 contiguous carriers for CATV infrastructure applications. A choice of two optional 2× interpolation filters is available to simplify the postreconstruction filter by effectively increasing the DAC update rate by a factor of 2. In Mix-Mode operation, the AD9119/AD9129 can reconstruct RF carriers in the second and third Nyquist zone while still maintaining exceptional dynamic range up to 4.2 GHz. The high performance NMOS DAC core features a quad-switch architecture that enables industry-leading direct RF synthesis performance with minimal loss in output power. The output current can be programmed over a range of 9.5 mA to 34.4 mA.

The AD9119/AD9129 include several features that may further simplify system integration. A dual-port, source synchronous LVDS interface simplifies the data interface to a host FPGA/ASIC. A differential frame/parity bit is also included to monitor the integrity of the interface. On-chip delay locked loops (DLLs) are used to optimize timing between different clock domains.

A serial peripheral interface (SPI) is used to configure the AD9119/AD9129 and monitor the status of readback registers. The AD9119/AD9129 is manufactured on a 0.18 μm CMOS process and operates from +1.8 V and −1.5 V supplies. It is supplied in a 160-ball chip scale package ball grid array.

  1. High dynamic range and signal reconstruction bandwidth support RF signal synthesis up to 4.2 GHz.
  2. Dual-port interface with double data rate (DDR) LVDS data receivers supports the maximum conversion rate of 2800 MSPS.
  3. Manufactured on a CMOS process, the AD9119/AD9129 uses a proprietary switching technique that enhances dynamic performance.
  • Broadband communications systems CMTS/VOD
    Wireless infrastructure: W-CDMA, LTE, point-to-point Instrumentation, automatic test equipment (ATE) Radars, jammers

EVAL-AD9119 Circuit Diagram

Product Details

The AD9119 Evaluation Board connects to the Analog Devices Digital Pattern Generator (DPG2) to allow for quick evaluation of the AD9119. The DPG2 allows the user to create many types of digital vectors and transmit these at speed to the AD9119 in any of the AD9119 operating modes. The AD9119 evaluation board is configured over USB with accompanying PC software.
