Part Number: DAC38RF84 Hi Team,
I don't have an EVM board, and I am using a self-made board to debug the DAC38RF84, and now I have a strange problem. I use FPGA to generate a 64-point sine signal (I channel) and cosine (Q channel). Each sampling point…
Part Number: DAC38RF84 Other Parts Discussed in Thread: LMK04828 Hi,
I am using the DAC38RF84 in my design and when I read the status register, I am getting a high bit at bit 0 of status register 0x05. This makes me understand that the internal PLL…
Part Number: DAC38RF84 Hi Team,
Could you please check the below customer error codes to make sure i'm 100% correct. Customer is evaluating DAC38RF84, and is testing using LMFSHd = 82121, interpolation 6x, 8x. From table 44 of the datasheet this configuration…
Part Number: DAC38RF84 Hi team,
One of our customer's issues, I'm forwarding it below, could you please provide some troubleshooting suggestions?
I do not have an EVM board and I am debugging the DAC38RF84 with a homemade board and have a strange…
Part Number: DAC38RF84 Other Parts Discussed in Thread: TPS62085 , TPS563201 , TPS563240 , TPS563211 , TPS62913 Hi,
The power supply scheme in the datasheets suggest the TPS62085 - a 3A step-down with integrated switch (external inductor).
These…
Part Number: DAC38RF84 Hi Experts,
Good day. I have this query from client:
It shows that two NCO of DAC38RF84 can switch to change one frequency to another frequency quickly. Page #35 of DAC38RF84 D/S, it showed the outputs of NCO1 and NCO2 were…
Part Number: DAC38RF84 Other Parts Discussed in Thread: DAC5681
Hello, Can you provide a spur calculator spreadsheet for the DAC38RF84? I found a posting for a calculator for the DAC5681 (below), but it is missing a lot of features of the RF sampling…
Part Number: DAC38RF84 Hi, there :
Bit 0 of "Divided Output Clock Configuration Register" in DIG_MISC page is EXTREF_ENA.
The description says it allows the chip to use external reference or internal reference.
Does it mean CLK_OUT use either DACCLKP…
Part Number: DAC38RF84 Other Parts Discussed in Thread: DAC38RF82 , , DAC38J84 Hi,
There is one customer who meet a question during using DAC38RF84 . The sync pin of both channel are high when power up, even though no clock.
As my opinion, according…
Part Number: DAC38RF84 Other Parts Discussed in Thread: DAC38RF80 , AFE7950
Dear sir,
We try to use DAC38RF84 to generate a frequency hopping tones through internal NCO of DAC38RF84.
1. Because we don't require baseband modulation, can the DAC38RF84…
