AD9789BBCZ

The AD9739 and AD9739A are high performance, high frequency 14-bit DACs that provide sampling rates of up to 2.5 GSPS. These devices

permit multicarrier generation at up to the Nyquist frequency in baseband mode, and utilizing their unique mix-mode functionality,

they can generate carriers of up to 2.7 GHz in the second and third Nyquist zones. They include a dual-port LVDS interface to readily

interface with existing FGPA/ASIC technology to facilitate the maximum baseband signal synthesis bandwidth of 1.25 GHz. Unlike the

AD9739A, the AD9739 features a multichip synchronization feature that allows the synchronization of multiple transmit channels (see

block diagrams below). With 1.1 W power consumption at the full sampling rate, the AD9739 and AD9739A RF DAC IC devices provide

the lowest power and smallest package-size solution for synthesizing up to 1 GHz of bandwidth and output frequencies below 2.5 GHz

in multicarrier transmit systems. They eliminate the need for discrete multichannel or multistage design by integrating all the bandwidth

and output frequency capabilities in a single chip.
