Dear Experts,   I am planning to use the ADAU1979 in an unorthodox manner. I would like to use asynchronous sources for the serial audio port clocks (LRCLK, BCLK) and the PLL MCLKIN. Is it possible at all? I can select the sampling frequency freely to be either higher or lower than the serial port frame frequency.   If it is possible, I… (Show more)

According to the technical documents of this connection, the reference voltage will not change with the change of the RT?

AD-FMCDAQ2-EBZ board has a clock generator on the board? Can we connect to an external clock source as a reference for PLL? In my case I would like to derive my clocks from 10.24 MHz clock.   Please let us know.   Best Regards   Mallesh

Hello, I cannot find AD5165 wiper position after power-up. According to AN1291, there are two type of DigiPot that have POR or not. And default state of wiper position is depend on POR integration or not in DigiPot.   If AD5165 have POR, default wiper position is mid scale, I suppose. But I cannot find such a information in Datasheet. So… (Show more)

The datasheet mentioned 'Power-on reset with brownout detection' as a feature but without any further details? Can more details be supplied? I have a design that if I power cycle too quickly (~2 seconds) then the DAC chip ignores the serial data-stream. Does the power rails need to fall to a low voltage to reset the chips logic?

Hi All,   I have problem accessing SPI via FMC, the chip select CS1 from FMC connector will not pass through the voltage translator U10 (FXLA108BQX). I have noticed that the OE_N pin of U10 is high so it means it is disabled. Is there any application sofware for this board (AD9152-FMC-EBZ) so that the OE_N can be asserted or enable the SPI access… (Show more)

Hi I have c connected my circuit as in b battery operated option in ad736..my input is phase voltage which is coming out of 3 phase inverter..input properties are 20khz pulse train with varying widths with 72vdc amplitude... i decimated it to 300mv (yellow graph) using resistor divider network.but my output is not dc but same pulse wave as shown… (Show more)

AD9739 work at mix mode , can output RF signal,with center frenquency at 1.7GHz, and bandwidth = 300MHz? AD9739 Clk frequency is 2GSPS thanks!

I want to getting a voltage level from AD9236. But when I test AD9236 (ADC) It is difficult to anlayze a signal with low frequency. As this reason, I can't get a DC(direct current) voltage value.   ADC is always used for fluctuating signal? As far as I know, ADC is convert analog level to digital data.   (Left one is squre wave sampled… (Show more)

Hello,   I use the AD5141 on our board and sometimes, the analog value of the potentiometer doesn't change even if we try to load different value several times. The only way to solve it is to restart the power supply of the board or to apply a reset on the AD5141. Do you have some ideas which could explain this problem?   Thank you in…
