Product Summary
The DAC5688IRGCR 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 DAC5688IRGCR offers superior linearity, noise, crosstalk and PLL phase noise performance. The applications of the DAC5688IRGCR include Cellular Base Stations, Broadband Wireless Access (BWA), WiMAX 802.16, Fixed Wireless Backhaul, and Cable Modem Termination System (CMTS).
