32-Bit Programmable NCO On-Chip 2×–16× PLL Clock Multiplier With
Bypass Mode Differential Scalable Current Outputs:2 mAto mA On-Chip 1.2-V ReferenceThe DAC5686isa 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 designedto 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 modesof 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 useof relaxed analog post-filtering.
Single-sideband mode provides an alternative interfaceto the analog quadrature modulators. Channel carrier
selectionis performedat baseband by mixingin the ASIC/FPGA. BasebandI andQ from the ASIC/FPGA are
inputto the DAC5686, whichin turn performsa complex mix resultingin Hilbert transform pairsat the outputsof
the DAC5686's two DACs. An external RF quadrature modulator then performs the final single-sideband
up-conversion. The DAC5686's complex mixing frequencies are flexibly chosen with the 32-bit programmable
NCO.
