  • RE: PCM4222: PCM4222 analog input interface

    Hi Jung, I would look at Your SCLK input. jitter on this signal can worsen THD. Also please try to use low voltage coefficient capacitors for C3, C12 (capacitors whos capacitance does not change much across voltage) such as a film capacitor. this note…

  • PCM4222: gain and reference tempco

    Part Number: PCM4222 We are using this part in a measurement system for precision audio measurement. We are trying to bound limits of measurement change between calibration procedures. However the data sheet for the part doesn't have any temperature coefficient…

  • PCM4222: BCK clock rate in PCM output mode (Normal speed, Slave, Left Justified)

    TI Thinks Resolved
    Part Number: PCM4222 Hello, I'm trying to understand how to set the BCK clock input rate when using the ADC in PCM mode, Left-Justified data format, Slave Mode, Normal speed mode quoting the datasheet (pag. 21): For the I2S and Left-Justified data…

  • PCM4222: THD+N questions at 48Khz and 96Khz sample rate

    TI Thinks Resolved
    Part Number: PCM4222 Hello, About the THD+N, I have a question to interrupt you. The dynamic range is about 121dB, that is to say the ADC quantized noise is about-121dbfs. But when the sample rate is 48Khz and 96Khz, the THD+N are both 108dB under the…

  • PCM4222: Running in slave mode

    Resolved
    Part Number: PCM4222 Hello. 4 PCM4222's in a system, one master and three slave. Do all four devices' control pins get used (FS0/FS1, OWL0/OWL1, and FMT0/FMT1) or only the master device? Any input is appreciated.
