AD9789BBCZ Datasheet PDF - ADI

The AD9789BBCZ is a 14-bit Digital-to-analog Converter (DAC) with 4-channel signal processing. The flexible digital interface can accept up to 4-channel of complex data. The QAM encoder supports constellation sizes of 16, 32, 64, 128 and 256 with SRRC filter coefficients for all standards. The on-chip rate converter supports a wide range of baud rates with a fixed DAC clock. The digital up-converter can place the channels from 0 to 0.5 x fDAC. This permits four contiguous channels to be synthesized and placed anywhere from dc to fDAC/2. The AD9789 includes a serial peripheral interface (SPI) for device configuration and status register read-back. The AD9789 operates from 1.5, 1.8 and 3.3V supplies for a total power consumption of 1.6W. The clock receiver powers up muted to prevent start-up noise.
