The AD9789BBCZ is a 14-bit RF digital-to-analog converter (DAC) from Analog Devices, designed for high-speed broadband transmission systems. It supports a maximum conversion rate of 2.4 GS/s and integrates an oversampling interpolating DAC architecture with on-chip QAM encoding, rate conversion, and digital upconversion for direct RF synthesis.
The DAC provides a single unbuffered current output with unipolar polarity and differential output capability. It accepts LVDS parallel or standard parallel data interfaces and supports both external and internal voltage references. Typical settling time is 13 ns. Power dissipation is 1.6 W typical and 1.7 W maximum under specified conditions. The device requires three supply rails: 1.5 V, 1.8 V, and 3.3 V nominal.
In a DOCSIS 3.0 test configuration, the AD9789 demonstrates ACLR of -75 dBc at fOUT=200 MHz across the full 47 MHz to 1 GHz band, with -72 dBc (noise) and -67 dBc (harmonics) at fOUT=800 MHz, and unequalized MER of 42 dB. These characteristics suit broadband communications, CMTS/DVB systems, cellular infrastructure, and point-to-point wireless transceivers.
The AD9789BBCZ is housed in a 164-ball CSPBGA (12 mm x 12 mm) package with 0.96 mm height, designed for surface-mount assembly. It operates over -40°C to +85°C and is supplied in tray packaging.
The AD9789BBCZ requires three supply rails: 1.43 V ~ 1.58 V (1.5 V nominal), 1.71 V ~ 1.89 V (1.8 V nominal), and 3.14 V ~ 3.47 V (3.3 V nominal).
It is available in a 164-LFBGA/CSPBGA package, specifically a 164-CSPBGA measuring 12 mm x 12 mm.
-40°C to +85°C.
The manufacturer page lists the AD9789BBCZ as RoHS compliant, but this is not independently verified. The page also reports the part as containing lead, which may be subject to an exemption.
The typical settling time is 13 ns.
It uses an oversampling interpolating DAC architecture.
The device supports LVDS parallel and standard parallel data interfaces.
