The DAC5688 is a dual-channel 16-bit 800 MSPS digital-to-analog converter (DAC) with dual CMOS digital data bus, integrated 2x-8x interpolation filters, a fine frequency mixer with 32-bit complex numerically controlled oscillator (NCO), on-board clock multiplier, IQ compensation, and internal voltage reference. Different modes of operation enable or bypass various signal processing blocks. The DAC5688 offers superior linearity, noise, crosstalk and PLL phase noise performance.

The DAC5688 dual CMOS data bus provides 250 MSPS input data transfer per DAC channel. Several input data options are available: dual-bus data, single-bus interleaved data, even and odd multiplexing at half-rate, and an input FIFO with either external or internal clock to ease interface timing.
