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 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…

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 ref of 2560Mhz to…
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 DAC…
Part Number: DAC38RF83 Other Parts Discussed in Thread: LMK04828 , I use a dac38rf83 with LMK04828 as the JESD204B clock generator and Intel Arria10 FPGA as JESD204B TX. JESD204B parameters are LMFSHd = 44210, K=32(Dual DACs, 1 IQ pair per DAC, 2 lanes per…

Hi,
When the NCO is set to 767MHz, a signal of about 53dBc (like phase noise) is generated from the modulated signal in the range of about 10MHz centered on the modulated signal of about…
Part Number: DAC38RF83 Dear Team,
My customer is using multiple DAC38RF83 on board operating with their internal PLL.
We’re trying to understand how we can cut the PLL auto tune time to the minimum ?
If we know the device temperature , can we preset…
Part Number: DAC38RF83 Dear Team,
My Customer would like to understand Table 4. SerDes PLL Modes Selection in datasheet.
It connects MPY hex value to actual multiplier. The default MPY value is 00010100 - it is 0x14 in hex. There's no such value in this…
