TFT LCD display, with keys, make the interface operation more humane, support sine wave, square wave transmission, square wave adjustable duty cycle, equipped with filter circuit and post-amplifier output port. 180MHZ clock rate, 10-bit DAC with 6X reference clock multiplier and simplified control interface of high-speed comparator with hysteresis characteristics: parallel or serial asynchronous loading format comparator jitter: less than 80PS peak value (20MHZ) AD9851 is a highly integrated device, using advanced DDS technology, built-in a high-speed, high-performance digital-to-analog converter and comparator, which together constitute a digital programmable frequency synthesizer and clock generator. When the clock source is used as the reference, AD9851 can produce a frequency stable phase programmable digital analog output sine wave. The sinusoidal wave can be directly used as a frequency source or internally converted into a square wave suitable for agile clock generator applications. Low power consumption: 555MW (180MHZ) SFDR Greater than 43 DB (70 MHZ AOUT) Name: AD9851 High Speed DDS Module Power Supply: 7-9V(Recommended 7V) Colour:Green Material:plastic Size:100mm x 60mm Package Contents: 1 x Function signal generator Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
