  • PCM1802: Rise and fall times

    Part Number: PCM1802 Hi team, I know that the rise and fall times are specified to be less than 10ns, but I would like to use a clock that exceeds 10ns to prevent EMI. Would this be possible under certain conditions? For example, by using a BCK period of…

  • PCM1802: Sharp noise spikes on otherwise-clean data output

    Part Number: PCM1802 Other Parts Discussed in Thread: PCM1808 , To whom it concerns, We're currently developing the second revision of a product which uses four PCM1802s to sample eight analog inputs. One acts as the master and provides bit and word…

  • PCM1802: About the duty ratio condition of the system clock

    Resolved
    Part Number: PCM1802 Hi team, There is no duty ratio specified in the system clock, but as long as the minimum pulse width of 7ns is observed, is there any problem with any duty ratio? If so, what is the acceptable duty ratio range? Also, is it correct…

  • PCM1802: Noisy VREF1.

    TI Thinks Resolved
    Part Number: PCM1802 The lack of PSR data for this device is a hindrance. The datasheet just says that VCC should be clean. What does that mean? A battery? I have a clean VREF2 (-106dBu) but my VREF1 (midrail) is much noisier (-85dBu) for some reason…

  • RE: PCM1822: Low pass filter cut of at 48Hz?

    Hi Daveon. plot attached. No any AC-coupling in circuit. Signal is directly from signal generator. I have moved from PCM1802. With Pcm1802 I can switch off this filter. and it works fine. But in pcm1822 there is no such option. It is fixed at 0.00025xFs…

  • PCM1802: Replacing PCM1803A with PCM1802

    Resolved
    Part Number: PCM1802 Other Parts Discussed in Thread: PCM1803A , Hi, Are there any concerns if replacing PCM1803A with PCM1802? Is my understanding correct that FSYNC pin should be pulled-up to VDD with the slave mode(FMT1=0, FMT0=0, MODE1=0 and MODE0=0…

  • PCM1802: Effect of VCC degradation

    TI Thinks Resolved
    Part Number: PCM1802 Hello Support team, We understand VCC for PCM1802 is required to be over 4.5V as mentioned in the page6 of its datasheet: But in our design, depending on noise, temperature and other conditions, it turned out that VCC may momentarily…
