AD9789BBC

Digital To Analog Converters Overview

The AD9789BBC is a 14-bit, 2400 MSPS RF digital-to-analog converter (DAC) featuring integrated four-channel signal processing. It combines QAM encoders with SRRC filters, 16× to 512× interpolation, rate converters, and digital upconverters for direct synthesis of DOCSIS or DVB-C channels. The device supports flexible data interfaces including CMOS and LVDS, configurable from 4-bit to 32-bit widths. It operates on 1.5 V, 1.8 V, and 3.3 V supplies with a typical power consumption of 1.6 W at full speed. The component is housed in a 164-ball CSP-BGA package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BBC' against the manufacturer's current ordering guide to confirm pinout and package configuration. Ensure that the required supply voltages (1.5 V, 1.8 V, and 3.3 V) are available within specified tolerances for the target application environment.

Digital To Analog Converters Selection Notes

Select this component when high dynamic range and low noise spectral density are required for multi-channel RF synthesis. The integrated digital upconversion reduces external FPGA logic requirements. Verify that the system clock jitter does not degrade the SFDR performance below the required threshold for the specific output frequency.
