Sam, About the routing constraints: Obviously each diff pair needs to be matched length. But also, all channels need to be matched length up to the common point. With CW doppler the phase is very...

Shadi, I don't think there exists any ini file for the AFE5808 , we will have to generate one. In the meantime, please the ADS528x. I think this is the same format. By the way, the TSW1405 will only...

Hi Haibo, Could you show me the circuits around the tsc2046 ? How many units have you tried so far? Did you find any device that work normally? When this issue happens, will the device recover and work...
View ArticleForum Post: RE: AFE5801- DCLK 60 MHz or 120 MHz?
Hello Chuck: Thanks for the clarification. Assuming FCLK (frame clock) = 10 MHz, rate at which the inner or deserialize While Loop should execute is 60 MHz. FYI- We need to build DDR logic block +...

Hi Patrick, I'm afraid no because the physical features of touch panels are beyond the control of any resistive touch controller. If the two ITO layers of a touch panel are not bent enough by force to...
