• ADAV803 problems


    I have some problems with ADAV803.

    PLL falls apart after each MCU reset almost right away (even after the initialization of the IC with 30sec delay if the jamming started by then).


    I folowed the AN-910, by setting the VCO test register (0x7F…

  • RE: Does ADAV803 have the capability to decode multichannel S/PDIF and output TDM8 serial data?

    I have never used the ADAV803, but according to page 24 of the Rev. A datasheet (http://www.analog.com/static/imported-files/data_sheets/ADAV803.pdf), I think it can only handle 2 audio channels on the S/PDIF receiver/transmitter.

  • Disabling CPLD on EVAL-ADAV803/EVAL-ADAV801

    I have an EVAL-ADAV803 board which I am trying to connect to a Atmel AT91SAM development board, with Linux, via I2C and I2S. I have the kernel module loaded on the AT91 and I would like to prevent the CPLD from connecting to the ADAV803. How can I do…

  • What is the "rate register" on the ADAV803 and how do you use it?

    I'm having trouble getting the SRC to work properly in the ADAV803.  What is the "rate register" and how do you use it?

  • ADAV803 Internal Registers Problems

    Hi all,

    I am currently programming the ADAV803 using the I2C serial interface protocol so that to program the internal control registers.

    I found a problem that in a range of certain registers, from (0x60 to 0x60), When I send a byte of data so that…

  • ADAV803 SRC clock question

    Table 2 on page 4 of the ADAV803 datasheet lists SRS MCLK Min = 138 x Fsmax but the text on page 21 states "The SRC master clock is expected to be equal to 256 times the output sample rate."   These appear to be conflicting statements..  Please…

  • RE: ADAV803 Question Please help me!

    The ADAV803 does not store audio data in internal memory. You will have to feed your audio data to the codec through either the analog input or digital serial input (I2S) port.

  • RE: S/PDIF + analog audio to I2S

    Hi alon.bender,

    The ADAV801/803 are your best bet for this application. No other parts offer both stereo ADCs and S/PDIF. ADAV801 is SPI controlled and the ADAV803 is I2C control.
