Data Sheet 11-/14-Bit, 2.5 GSPS, RF Digital-to-Analog Converters AD9737A/AD9739A FEATURES Direct RF synthesis at 2.5 GSPS update rate DC to 1.25 GHz in baseband mode 1.25 GHz to 3.0 GHz in mix-mode Industry leading single/multicarrier IF or RF synthesis Dual-port LVDS data interface Up to 1.25 GSPS operation Source synchronous DDR clocking Pin compatible with the AD9739 Programmable output current: 8.7 mA to 31.7 mA Low power: 1.1 W at 2.5 GSPS APPLICATIONS Broadband communications systems DOCSIS CMTS systems Military jammers Instrumentation, automatic test equipment Radar, avionics SDIO SDO CS SCLK FUNCTIONAL BLOCK DIAGRAM RESET IRQ AD9737A/AD9739A 1.2V SPI DAC BIAS VREF I120 LVDS DDR RECEIVER DB0[13:0] DATA LATCH IOUTN DCI TxDAC CORE IOUTP 4-TO-1 DATA ASSEMBLER DATA CONTROLLER LVDS DDR RECEIVER DB1[13:0] DCO CLK DISTRIBUTION (DIV-BY-4) DLL (MU CONTROLLER) 09616-001 GENERAL DESCRIPTION The AD9737A/AD9739A are 11-bit and 14-bit, 2.5 GSPS high performance RF DACs that are capable of synthesizing wideband signals from dc up to 3 GHz. The AD9737A/AD9739A are pin and functionally compatible with the AD9739 with the exception that the AD9737A/AD9739A do not support synchronization or RZ mode, and are specified to operate between 1.6 GSPS and 2.5 GSPS. By elimination of the synchronization circuitry, some nonideal artifacts such as images and discrete clock spurs remain stationary on the AD9737A/AD9739A between power-up cycles, thus allowing for possibl.
