Re: ADV7401BSTZ-110 - Hsync Issue
Hi Dave, There is one more aspect to be done. Contrast for the image or video need to be adjusted. Please let me know if the contrast can be adjusted in CP mode. Datasheet shows that only SDP has the...

Hi Igal, I don't know that it won't work-- but there is certain no script for it officially or otherwise. I suspect we have no source for that format and have never tried it so wouldn't be able to...

Hello Rajesh, What have you done with the ALSB bit? If it's not responding to address 0100000 (0x40), then ALSB is probably high so you should be witing to 01000010 (0x42). This is the address in the...
View ArticleRe: AD5421 : Cin pin
Hi there, Yes, looking at the slew rate and settling time specs of the AD5421, it should be possible to use the AD5421 with this FSK signal. Do you mind me asking why you are using this form of...

Hi, Please use the "SPI PROM" option in the Loader options. This will instruct the Loader to perform bit reversal. This is necessary as most SPI Flash parts work in MSB first, while the SHARC is...

Hi Niels, The AD5422 should be fine to operate at an update rate of 100kHz in the manner in which you describe, especially given the fact that you require small DAC value changes. Do you require...

Mainly two reasons: The VDMA can not keep up with the bandwidth of the DAC. It will run dry very quickly and we will have an underflow. So in order to bridge the gap between a low speed VDMA engine and...

Hi Niels, The AD5420 has the same settling time specs as the AD5422. The only difference is that it is Iout only, rather than Vout/Iout. In terms of step size vs settling time, looking at the "4 mA to...
