  • ADC3683: Can ADC3683 work with 100kHz input signals?

    TI Thinks Resolved
    Part Number: ADC3683 Hi teams, My customer is using ADC3683 on their products. When they input high frequency signals (sine wave, 600mVpp@1Mhz, 10Mhz,), ADC3683 can work well, with THD about -80dB. However, when input an low frequency signal (100kHz,…

  • ADC3683: ADC3683 deserializer source code to interface with Xilinx FPGA

    TI Thinks Resolved
    Part Number: ADC3683 Hello, Our design team is evaluating ADC3683 using DC134 eval board for our future product line. I was looking for an 18-bit ADC deserializer source code to interface with Xilinx Ultrascale+ I am a bit confused about the need for…

  • ADC3683: Glitch and input of ADC

    TI Thinks Resolved
    Part Number: ADC3683 Other Parts Discussed in Thread: THS4551 , , , THS4541 Hi, I used THS4551 to drive ADC3683 and found large glitch (200mV peak) on the nodes V_P and V_N. The waveform is scope calculation result V_P - V_N. The scope bandwidth is 200MHz…

  • ADC3683: FCLK DIV Register value

    Resolved
    Part Number: ADC3683 Hi team, In Fig.8-53 and Table 8-22 in the D/S said that initial value of Register"0x19" after the reset is "0x00." but my customer got "0x10"(FCLK DIV=1) as actual measurement. It is possible to write…

  • ADC3683: Bit 17 high with test pattern 0 (or any other)

    Resolved
    Part Number: ADC3683 Hi, Something small I do not fully comprehend: when I enter 'Custom pattern' and pattern value 0, I see in the HDSC application that bit 17 is high -> 131072. When 131072 is entered as a test pattern the output is truly 0…

  • ADC3683: Operations without frequency locked DCLKIN

    TI Thinks Resolved
    Part Number: ADC3683 Other Parts Discussed in Thread: CDCE6214 Hi, the data sheet of the adc3683 states that the dclkin clock needs to be frequency locked to the sample clock. I have an application where I don't have equidistant sampling points and hence…

  • ADC3683: differential input impedance for simulating AAF and Glitch Filter

    TI Thinks Resolved
    Part Number: ADC3683 I do not really understand the function / the effect of the recommended Glitch Filter between AAF and ADC. The description in the ADC data sheet is not detailed enough for me. The EVM uses different values for the Glitch Filter than…
