DAC5688

The DAC5688 is a dual-channel 16-bit 800 MSPS  Input Data digital-to-analog converter (DAC) with dual CMOS  adigitfainl edatafrebquuse,nicnytegrmatiexedr2x-w8ixthinte3r2p-obliat tiocnofmiltpelresx,  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.

Interface Input data can interpolated 2x, 4x or 8x by on-board  sdtigoipta-bl ainndtearpttoelnautiantgionF.IR filters with over 80 dB of 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 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.
