Part Number: DAC38RF83 Hello,
Is it possible to change the FIR filter coefficient values of the DAC38RF83, from those listed in Table 35 of the datasheet? I was hoping there might be some undocumented register(s) for doing this. We'd like to change…
Hello Scott,
I am adding some clarifications and distinctions to this thread in the case that it should be referenced in the future. To clarify the LP filter is better described as being maintained by the PFD and charge pump rather than being manipul…
Part Number: DAC38RF83 What are the min and max Vcom for the DAC38RF38 SYSREF input? Datasheet only says 0.5V for typical. Also, what is the min Vi(dPP)? The datasheet only gives typ (800mv) and max(2000 mv). We are driving this with a signal that has…
Part Number: DAC38RF83 Other Parts Discussed in Thread: LM27761 , Hi In my board DAC38RF83 current consumption at VEE18N power rail is 340 mA. Which is to high, relative to datasheet. Power supply schematic is the same as in EVB. I measured it trough small…
Part Number: DAC38RF83 Hello,
My application needs a Carrier Freq of 1030MHz and we are currently looking into the DAC38RF83/90.
We are trying to understand where the Carrier is generated. Is it the NCOs that set the Carrier Quadrature signals?
Please…
Part Number: DAC38RF83 Hello, In my design I don't want to use external SYSREF since I use only a single IC. In the datasheet, I found few registers that were possible designed for (Internal SYSREF Register (LCMGEN), Counter for Internal SYSREF Generator…
Part Number: DAC38RF83 DEARS.
We are considering the development of DAC38RF83
What is the register that checks the PLL LOCK and JESD204B PLL LOCK?
What is the normal value of PLL LOCK and JESD204B PLL LOCK?
Thank You

Hi
Just to be sure.
How many SYSREF triggers the DAC38RF83 received, if the SYSREF input goes from logic '0' to logic '1' and stay at '1'?
Thanks
