  • PCM4222EVM: Noisy 96 khz

    TI Thinks Resolved
    Part Number: PCM4222EVM Other Parts Discussed in Thread: PCM4222 Hi there, I have this 4222 evaluation board that works perfectly at 44.1khz. No noise, sounds amazing. At 96khz sample rate there is noise without anything plugged into the analog inputs…

  • PCM4222EVM: Unknown clock oscillator on received board

    TI Thinks Resolved
    Part Number: PCM4222EVM Hi, According to the BoM, the board has two Pletronics oscillators, in particular SM7745HSV-22.5792M. However on the board received I can see something else was used. Unfortunately I couldn't identify it, so maybe you could clarify…

  • PCM4222EVM: PCM4222

    Part Number: PCM4222EVM Some questions are raised for OVFR/OVFL pin. When input 1Khz with high amp~7Vpp, we could see the pin asserted. But when input frequency increase to 50khz, we cannot see it asserted. Could you specify why it cannot work with higher…

  • PCM4222EVM: Using BCK/LRCK from I2S Serial Port Header

    Part Number: PCM4222EVM Other Parts Discussed in Thread: PCM4222 Hi, We're currently assessing different high-end audio ADCs EVM, and after reading the PCM4222EVM guide here http://www.ti.com/lit/ug/sbau124/sbau124.pdf I'm a bit confused if the EVM…
