AD9734

Data Sheet 10-/12-/14-Bit, 1200 MSPS DACS AD9734/AD9735/AD9736 FEATURES Pin-compatible family Excellent dynamic performance AD9736: SFDR = 82 dBc at fOUT = 30 MHz AD9736: SFDR = 69 dBc at fOUT = 130 MHz AD9736: IMD = 87 dBc at fOUT = 30 MHz AD9736: IMD = 82 dBc at fOUT = 130 MHz LVDS data interface with on-chip 100 Ω terminations Built-in self test LVDS sampling integrity LVDS-to-DAC data transfer integrity Low power: 380 mW (IFS = 20 mA; fOUT = 330 MHz) 1.8/3.3 V dual-supply operation Adjustable analog output 8.66 mA to 31.66 mA (RL = 25 Ω to 50 Ω) On-chip 1.2 V reference 160-lead chip scale ball grid array (CSP_BGA) package APPLICATIONS Broadband communications systems Cellular infrastructure (digital predistortion) Point-to-point wireless CMTS/VOD Instrumentation, automatic test equipment Radar, avionics GENERAL DESCRIPTION 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 ...
