Hi wallman16,
We do not have VFC parts with a maximum output frequency of 5 MHz. The DDS parts such as the AD9830 could be used. The DDS part generates a waveform from a digital code. An ADC would be required to convert the voltage to a digital code…
This webcast will provide an introduction to clocks and frequency synthesis, clock terminology, timing and common applications. We will discuss Phase-locked loops (PLL), Analog PLLs, Digital PLLs and Direct Digital Synthesis.
Hi David,
The AD9835 does not have the Reset pin required so you will need to look at either the AD9834, AD9830 or AD9831. FQ_UP has the same functionality as the FSYNC pin.

Here is a handy table giving the truncated phase word size plus other useful features found in our DDS products.
什么是时钟？
常用的一些频率是多少？
五种主要类型的时钟芯片—— 模拟PLL、数字PLL、全数字PLL、直接数字频率合成器、通用振荡器，它们之间的区别是什么？各自的应用优势又是什么？

Frequently we're asked for help selecting a DDS with frequency sweeping capability, phase hopping, amplitude control etc. but until now the only way to answer that question was to go based on memory or to look at the datasheets for several DDS parts.…
Hi! Kevin, Thanks alot firstly, for helping on my queries. It helps.
As informed earlier, I'm possessing two signal generators 33250A (Agilents).
However, I want STEPWISE verrification of VPHS o/p swing from 30mV to 1.8 V using DDS (ad9834) as one…
