推荐一款业内时钟频率最高的DDS芯片，特点如下：
KEY FEATURES
• 32-bit frequency tuning word
• 13-bit ROM phase address resolution
• On chip DAC with 11 bit linearity
• Clock rate up to 3.2 GHz
• Sine wave generation up to 1.6 GHz
• Complementary analog waveform outputs with 50 Ω back terminations
• Carry bit RF output from phase accumulator for synchronization triggering of testing scope
or system applications
• Worst SFDR > 45 dBc (DC to 1.6-GHz Bandwidth) at a 3.2 GHz clock rate
• LVTTL/CMOS digital pattern control input
• Reset (RST) pin to initiate phase 0 starting state
• High speed strobe inputs (STR_P/N) to update the frequency word and DAC output
frequency
• High speed strobe inputs allow IT to be controlled by micro-controller or DSP chips
for real time chirping function
• Frequency update rate as fast as 8 clock cycles
• 3.5 W power consumption with a single -5V power supply
• 64-pin QFN package
