Back to TopDescription

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. Input data can interpolated 2x, 4x or 8x by on-board digital interpolating FIR filters with over 80 dB of stop-band attenuation.

The DAC5688 allows both complex or real output. An optional 32-bit NCO/mixer in complex mode provides frequency upconversion and the dual DAC output produces a complex Hilbert Transform pair. A digital Inverse SINC filter compensates for natural DAC Sin(X)/X frequency roll-off. The digital Quadrature Modulator Correction (QMC) feature allows IQ compensation of phase, gain and offset to maximize sideband rejection and minimize LO feed-through of an external quadrature modulator performing the final single sideband RF up-conversion.

The DAC5688 is characterized for operation over the industrial temperature range of -40°C to 85°C and is available in a 64-pin 9x9mm QFN package.
