  • ADS1675: Clock Jitter/SNR Relational Graph

    TI Thinks Resolved
    Part Number: ADS1675 Good afternoon, We're looking at using the ADS1675 for our design but could not find a specification in the datasheet that shows the relationship between clock jitter tolerance and SNR. Are there additional resources that show…

  • RE: ADS4225: CLKOUT Jitter and SNR

    Resolved
    Hi Yes...I'm confused about as you think. I understand the jitter is written by femto seconds. Thank you so much. Regards, Hideki

  • ADS131M04: Do you have any graph which shows relation between CLKIN jitter and SNR?

    TI Thinks Resolved
    Part Number: ADS131M04 Hello guys, One of my customers is considering using ADS131M04 for their new products. They want to use MSP430 clock output (8MHz) as ADS131M04 CLKIN. But the clockoutput has about +/-3% jitter. So they want to know how much SNR…

  • ADC12DJ3200QML-SP: SNR and clock jitter used in datasheet

    Resolved
    Part Number: ADC12DJ3200QML-SP Hi Team, We have a customer inquiry regarding figure 28 on page 29 of ADC12DJ3200QML-SP datasheet. 1. SNR is dependent on clock jitter. These are the measured results. 2. Do you know what the clock jitter is in these measurements…

  • ADS4449: Input Clock Jitter Requirements

    Resolved
    Part Number: ADS4449 Other Parts Discussed in Thread: ADC08D1520 , How can I determine the maximum amount of jitter tolerable from my clock source? The datasheet just says to use a very low jitter clock source. I've looked at the ADC08D1520 which gives…

  • RE: ADS4149: jitter and skew requirement for input clock

    Hi Chi, To achieve datasheet performance metrics of this device the lowest jitter clocking source should be used. Please find the below articles useful. In particular, the first part contains the equations you will be interested in which show the degradation…

  • RE: ADC3221EVM: Not working with TSW1400, "Clock from ADC EVM is not received by TSW board"

    Resolved
    Hi Yuan, The ADC jitter requirement can be found on page 47 of the datasheet (8.3.2.2 SNR and Clock Jitter). If you look at Figure 8-7, you can see how SNR degrades over input frequency due to external clock jitter. If you want the device to perform in…

  • RE: ADC3422: adc3422 output data issue

    Resolved
    Hello Amy, This is measurement of clock and calcuation of Jitter & SNR. What's min requirement of SNR? Also do you have any recommendation of oscillator part numbers?

  • RE: ADC12DJ3200QML-SP: Sampling clock phase noise requirements

    Hi Louis, See attached, this might help you in your analysis. I plugged in the numbers relative to the 3200-sp DS SNR numbers. As you can see, the jitter can get pretty high before there is a degradation in performance. Since your analog frequency band…
