The AD9736, AD9735, and AD9734 are high performance, high frequency DACs that provide sample rates of up to 1200 MSPS, permitting multicarrier generation up to their Nyquist frequency. The AD9736 is the 14-bit member of the family, while the AD9735 and the AD9734 are the 12-bit and 10-bit members, respectively. They include a serial peripheral interface (SPI) port that provides for programming of many internal parameters and enables readback of status registers.
A reduced-specification LVDS interface is utilized to achieve the high sample rate. The output current can be programmed over a range of 8.66 mA to 31.66 mA. The AD973x family is manufactured on a 0.18 μm CMOS process and operates from 1.8 V and 3.3 V supplies for a total power consumption of 380 mW in bypass mode. It is supplied in a 160-lead chip scale ball grid array for reduced package parasitics.
Product Highlights
- Low noise and intermodulation distortion (IMD) features enable high quality synthesis of wideband signals at inter-mediate frequencies up to 600 MHz.
- Double data rate (DDR) LVDS data receivers support the maximum conversion rate of 1200 MSPS.
- Direct pin programmability of basic functions or SPI port access offers complete control of all AD973x family functions.
- Manufactured on a CMOS process, the AD973x family uses a proprietary switching technique that enhances dynamic performance.
- The current output(s) of the AD9736 family are easily configured for single-ended or differential circuit topologies.
Applications
- Broadband communications systems
- Cellular infrastructure (digital predistortion)
- Point-to-point wireless
- CMTS/VOD
- Instrumentation, automatic test equipment
- Radar, avionics
