  • DAC5688: Frequency Modulation with DAC5688 — Avoiding NCO Accumulator Reset on Frequency Change

    TI Thinks Resolved
    Part Number: DAC5688 Tool/software: Hi everyone, I'm currently working on implementing frequency modulation using the DAC5688. I understand that in order to continuously change the output frequency, I need to update the Frequency Tuning Word (FTW) and…

  • ADS5404: Use of hi-speed ADC ADS5404 (or ADS5402) and DAC DAC5688 for WiFi project

    Part Number: ADS5404 Other Parts Discussed in Thread: ADS5402 , DAC5688 Tool/software: For our forth coming EVB development for WiFi project we are looking for high speed ADC and DAC that can support variable sampling rates from 40 to 320Msps for ADC…

  • DAC5688: CLKO output levels

    TI Thinks Resolved
    Part Number: DAC5688 Other Parts Discussed in Thread: SN74LVC1G125 , , Hi, I want to ask what are the logic levels of the CLKO_CLK1 pin, in output mode. Can you tell what the High and Low levels are, and whether or not it needs to be buffered when…

  • DAC5688: PLL CLOCK MODE

    Part Number: DAC5688 Other Parts Discussed in Thread: DAC5687 , DAC5686 Hi Im using the DAC5688 in PLL clock mode with CLK1 = 250 MHz and CLK2 = 250 MHz and the Frequency desired on PLL is 500 MHz (intp x2). For that M = 4 and N = 2. Sometimes i see…

  • DAC5688: CLK2/CLK2C LVDS or LVPECL

    TI Thinks Resolved
    Part Number: DAC5688 Other Parts Discussed in Thread: LMK04828 Hi Team, (1) Does CLK2/CLK2C accept LVDS? Or is LVPECL only available? (2) For LVPECL, I want to confirm how to set the clock interface. Per datasheet, it looks : - VCM = CLKVDD 1…

  • DAC5688: CONFIG26 io_1p8_3p3 default value

    TI Thinks Resolved
    Part Number: DAC5688 Other Parts Discussed in Thread: SN74AXC4T774 There's no information in the datasheet for default values for the CMOS IO threshold values. I'm looking to interface this DAC with a 1.8V IO FPGA bank

  • DAC5688: ESD Human Body Model Rating Data

    Part Number: DAC5688 Hi all, I am looking for the ESD characteristics of the DAC5688 but this data does not appear to be on the datasheet. Would it be possible to provide this data and then have the datasheet for this part be updated to include the…
