• The Analog Devices AD9850 is a CMOS, 125 MHz complete direct digital synthesiser on a single chip. It uses a single 5 V or 3.3 V supply, and with a 125 MHz clock, can generate a low-distortion sine wave or a square wave, from under 1 Hz up to about 60 MHz, with a tuning resolution of 0.0291 Hz. Full data on the device is available from ADI's web site: http://www.analog.com
