The DAC5686 is a dual-channel 16-bit high-speed digital-to-analog converter (DAC) with integrated 2×, 4×, 8×, and 16× interpolation filters, a numerically controlled oscillator (NCO), onboard clock multiplier, and on-chip voltage reference. The DAC5686 has been specifically designed to allow for low input data rates between the DAC and ASIC, or FPGA, and high output transmit intermediate frequencies (IF). Target applications include high-speed digital data transmission in wired and wireless communication systems and high-frequency direct-digital synthesis DDS.
The DAC5686 provides three modes of operation: dual-channel, single-sideband, and quadrature modulation. In dual-channel mode, interpolation filtering increases the DAC update rate, which reduces sinx/x rolloff and enables the use of relaxed analog post-filtering.
