AD9739BBCZ

The AD9739 is a high performance, high frequency 14-bit DAC that provides sample rates up to 2500 MSPS, permitting multicarrier generation up to the Nyquist frequency in baseband mode and second and third Nyquist zones in mix mode. It includes a serial peripheral interface (SPI) for configuration and readback of status registers. A dual-port LVDS interface is used to enable the high sample rate with existing FGPA/ASIC technology. The output current can be programmed over a range of 8.66 mA to 31.66 mA. The AD9739 is manufactured on a 0.18 µm CMOS process and operates from 1.8 V and 3.3 V supplies. It is supplied in a 160-ball chip scale ball grid array for reduced package parasitics.

Product Highlights

1. Low noise and intermodulation distortion (IMD) performance enable high quality synthesis of wideband signals up to 1 GHz.
2. A dual-port interface with double data rate (DDR) LVDS data receivers supports the maximum conversion rate of 2500 MSPS.
3. Manufactured on a CMOS process, the AD9739 uses a proprietary switching technique that enhances dynamic performance.
4. The current output(s) of the AD9739 are easily configured for single-ended or differential circuit topologies.
