AD9851BRSZRL FEATURES
180 MHz Clock Rate with Selectable 6 Reference Clock
AD9851BRSZRL GENERAL DESCRIPTION
The AD9851 is a highly integrated device that uses advancedDDS technology, coupled with an internal high speed, highperformance D/A converter, and comparator, to form a dig i tal lyprogrammable frequency synthesizer and clock generator func-tion. When referenced to an accurate clock source, the AD9851generates a stable frequency and phase-programmable digitizedanalog output sine wave. This sine wave can be used directly asa frequency source, or internally converted to a square wave foragile-clock generator applications. The AD9851’s innovativehigh speed DDS core accepts a 32-bit frequency tuning word,which results in an output tuning res o lu tion of approximately0.04 Hz with a 180 MHz system clock. The AD9851 con tainsa unique 6 REFCLK Multiplier circuit that eliminates theneed for a high speed reference oscillator. The 6 REFCLKMultiplier has min i mal impact on SFDR and phase noise char-ac ter is tics. The AD9851 provides fi ve bits of programmablephase mod u la tion resolution to enable phase shifting of itsoutput in in cre ments of 11.25°.The AD9851 contains an internal high speed comparator thatcan be confi gured to accept the (externally) fi ltered output of theDAC to generate a low jitter output pulse.The frequency tuning, control, and phase modulation words areasynchronously loaded into the AD9851 via a parallel or serialloading format. The parallel load format consists of fi ve it er a tiveloads of an 8-bit control word (byte). The fi rst 8-bit byte controlsoutput phase, 6 REFCLK Multiplier, power-down enable andloading for mat; the remaining bytes comprise the 32-bit frequencytuning word. Serial loading is accomplished via a 40-bit serial datastream entering through one of the parallel input bus lines. TheAD9851 uses advanced CMOS technology to provide this break-through level of functionality on just 555 mW of power dissipation(5 V supply), at the maximum clock rate of 180 MHz.The AD9851 is available in a space-saving 28-lead SSOP,surface-mount package that is pin-for-pin compatible with thepopular AD9850 125 MHz DDS. It is specifi ed to operate overthe extended industrial temperature range of –40°C to +85°Cat >3.0 V supply voltage. Below 3.0 V, the specifi cations applyover the commercial temperature range of 0°C to 85°C.
