Part Number: DAC38RF84 With DAC38RF84 configured for an output level of -7dBm (∼0.1 V)
There was an unintentional open circuit termination at the output of the device.
This causes the output power to be fully reflected back to the device at 2x the…
Part Number: DAC38RF84 Our design only uses 4 of the 8 JESD lanes available on the DAC. What should we do with the unused 4 lanes on our board. Can we leave the inputs unconnected or is there a recommended termination?
Part Number: DAC38RF84 Hello,
The datasheet appears to suggest that as DAC38RF84 has only one DAC, only one link is supported. Is that correct?
This would imply that the differential /SYNC1 pin pairs has no function on this device. If this is the case…
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 Hi!
I am struggling to understand section 8.3.1 in the DAC38RFxx datasheet. In a note below figure 51, it says "AC coupling is recommended for JESD204B compliance". This is also what I expected from other JESD204B documentation…
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: 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 is…
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 days there…
Part Number: DAC38RF84 Other Parts Discussed in Thread: TI-JESD204-IP Hello, I am looking to use the DAC38RF84 to generate a Tri-Level Synchronization Pulse for a 12G SDI Camera. Will this device be able to interface with the TI-JESD204-IP? I am using…
