anybody has the evaluation software for AD9832???? i urgently need it...
i enquired from the sales person from whom i procured the IC but he suggested to look out for it here...
please reply at the earliest
thanx in advance
am using ad9832 for 5Mhz frquency generation..
but i dont have a reference clock input...what i have is a simple sine wave generator...
how to provide a clock to the IC now
also can anybody suggest me how to check the DDS output..i mean on a scope…
I am looking to use the AD9832 as a local oscillator in a 50R system. It seems to me that the output current is too low to use with 50R mixers requiring > 1.4 V drive. This drivers the need for additional gain / driver stages which may introduce phase…
Im missing something... why you need to use AD9850 or AD9832...
Your output frequency is relatively low so, why you need to use the AD9832?
Corrected mistake. The AD9835 evaluation board was obsoleted a few years back. In it's place, the AD9832 evaluation board is recommended, but the AD9832 is limited to a max MCLK of 25MHz whereas the AD9835 can use a max MCLK of 50MHz.
I am using AD9832 to generate variable sine waves of 1Vp-p. I have connected the AD9832 according to the test conditions as shown in the data and FSYNC pin externally for sending data. I am sending the same data as prescribed in the application…
Please teach me AD9832.
Please teach the minimum value of MCLK.
I think no regulations in the data sheet.
But,ADIsimDDS displays the following message.
Frequency Error: Ref Clock Frequency exceeds the minimum Ref Clock frequency allowed for this…
Just to add that the AD9832 eval board can be powered externally, supporting the 2.5V Vio.
Following up on my last post, please find a preliminary application note which documents some write sequence examples for the AD9832/AD9835.
I am new to use of digital direct synthesis devices. I am designing a mainboard for a photoacoustic instrument.
This mainboard must generate three frequencies F1-F3 at three individually different phases PH1-PH3:
F1 = 16384Hz @ PH1
