Re: Output timings of ADV7181D between LLC and Px outputs.
1) T11 & T12 are good for LLC1 @ 27MHz2) LLC2 is just the divided down version of LLC1 so T11 & T12 should be valid for it also. Keep in mind the the frequency is slowed so you have more...

Hi Klaus, Thanks for your quick response. I looked into your suggestions, think I have it set up as it's supposed to be, but not sure about what I am seeing on my scope. I have attached the transmit...
View ArticleRe: ADV7401: ghosting video output from CP with 480p input.
Horizontal ghosting is often caused by reflections in the video signal. These are caused by routing issues and impedance mis-matches. First I'd examine the layout for video signal trace routing. The...
View ArticleRe: searching for a low-frequency, lock-in solution
Hi In my opinion 10Hz-100Hz is not a good choice. OPAmps have still high 1/f noise at that frequency. Better 500Hz-1000Hz. If you choose 10Hz the low pass filter needs to be very sharp to avoid the...

Re: DAQ2 reference design no longer talks with AD9144
Thank you for all of the information, Rejeesh. Is slowing down the DAC as simple as reprogramming the AD9523 to cut the DAC sample rate in half? Would that give enough margin for the current interface...
