  • ADAV801 duty cycle error

    Hello,

    a question regarding the SYSCLK2 output on ADAV801.

    At XIN I have a 27MHz crystal, at SYSCLK2 I need 24.576 MHz with 50% duty cycle.

    Because I use PLL2 and double sample rate (48 kHz x 2), I need to write in register 0x75 the value 0x10.

  • ADAV801: Change LRCLK at Serial Output Port from 96kS to 192kS

    Hello,
    if I use these settings (please see attachment for more information), I measure
    a LRCLK of 96 kS/s on the I2S interface at the serial output port, but we need 192 kS/s . Which register settings would be
    necessary for it?

    If I put a 192 kHz SP…
