A 200-MHz quadrature direct digital frequency synthesizer/complex mixer chip is presented. The chip synthesizes sine and cosine waveforms with a spectral purity of 84.3 dBc. The frequency resolution is 0.047 Hz with a corresponding switching speed of 5 ns with a tuning latency of 14 clock cycles. The chip is also capable of frequency, phase and quadrature amplitude modulation. These modulation capabilities operate up to the maximum clocking frequency. The chip provides the capability of parallel operation to achieve either 2 or 4 times the maximum frequency. The 0.8-μm triple level metal N-well CMOS chip has 52,000 transistors in a die area of 2.5×6.1 mm2. Power dissipation is 2 Watts at 200-MHz
