  THS3217: Interface design with current-sinking DAC3283

  TI Thinks Resolved

  Part Number: THS3217 Hi, I am designing the interface circuit for current-sinking DAC3283 using THS3217. I went through the TI's application note and tried to design the circuit based on the topology given in Figure 3. Since THS3217 has an...

  RE: TRF370417: TRF370417 LO leakage

  Hi, yes, correct. This is the typical LO leakage level. Adjusted carrier feedback through need to have DC offset correction between I and Q input. There are features in the DAC devices such as DAC3283 and DAC3484 family that have such feature to adjust...

  RE: DAC3283EVM: DAC3283 cannot output any current

  It's the key to solve the problem In the past, we use only output DAC, so this time, sink DAC cannot output current to driver external resistor. After tie the output to VCC throught a resistor, not we can see the sine waves. Thanks so much...

  RE: TRF372017EVM: Carrier leakage optimization

  Hi Noman, I have tested two types of EVMs: one TRF372017 EVM and one DAC3283 EVM with onboard TRF372017 to interface with the DAC3283. The TRF372017 EVM showed about -30dBm of LO leakage at 4.4GHz, while the DAC3283+TRF372017 EVM showed about -20dBm...

  DAC3283 clock rates

  Greetings. I wanted to double check that my clock calculations are correct for the DAC3283: What I need is I/Q (dual channel) which have an input sample rate of 80 MSPS each. Using DDR to send 2 bytes every clock cycle, but needing 2 clock cycles...

  RE: DAC3283 - Bi-directional SDIO in 4 wire mode - SPI Reads - Contention?

  Hi Kevin, In 4wire mode, the same data is driven out of the DAC on both the SDIO pin and the ALARM_SDO pin. If the FPGA is still driving the SDIO pin, then this will cause contention and corrupt the data on SDIO. In this case, ignore the data on the...
