Part Number: DAC38RF83 Hi Team,
We want to change the following registers while operating with the DAC38RF83:
(HEX values) 1C, 1D - we want to control the phase value (if these registers are the actual ones...)
Also we want to have the ability to…
Part Number: DAC38RF83 Hi Team,
I have a questions regarding DAC38rf83
After wakeup, the status in register: JESD Alarm for lane 0 (at address 0x64) is equal to 0xFF02 (page 116).
After clearing all bits, bit[1] remains set (0x0002).
My Questions…
Part Number: DAC38RF83 Tool/software: I'm bringing up a custom board, and the device seems to come up properly - but there is no output.
ALM_SYSREF_DET reads 0x0002, which seems fine.
ALM_SD_DET reads 0x0070, which is a little weird since there…
Part Number: DAC38RF83 Tool/software: I find the temperature reading low for a junction temperature. When I query the DAC38RF83 register 0x06, the TEMPDATA field returns a value around 42C. Is it normal that the temperature is so low when the DAC transmits…
Part Number: DAC38RF83 Tool/software: Is it normal that I have to modify for each of the cards that we have with a DAC38RF83, a different VCO range value (page 4, register 0x33: PLL Configuration 2 register)? I use the value 0x5128 for one DAC (PLL_VCO…
Part Number: DAC38RF83 There are 2 Serdes PLL lock indicators in SYSREF Alignment Circuit Alarms Register. ALM_SD0_PLL: Driven high if the PLL in the Serdes 0 block goes out of lock. ALM_SD1_PLL: Driven high if the PLL in the Serdes 1 block goes out of…
Part Number: DAC38RF83
Dear forum members,
We do have the problem of high phase noise when using the DAC38RF83/
We would like to get information where root cause of the high the phase-noise could be.
Environment:
1. Input…
Part Number: DAC38RF83 In datasheet 8.1.1 Start-up Sequence, "Toggle RESETB pin low then high." is showed. Is this necessary?
To avoid unintended reset, I will not connect RESTB pin to any controller such as CPU or FPGA, and place a pull-up resistor…
Part Number: DAC38RF83 Our RF modulator product uses DAC38RF83 with parameters as below: LMFS = 2221 clock 2376MHz interpolation x18 Current Serdes Lane Rate =2640MHz
This product gets register values of ALM_SD_DET(address = 0x04), SYSREF_ALIGN_R(address…
Part Number: DAC38RF83 Hi all
My question is about the -1.8V connected to the dac.
I see almost zero current consumption in the -1.8V DC (I verified that the voltage actually gets to the DAC), and I can't see any output frequency.
I have another…
