• ADAU1445 clock routing.

    I've got an I2S stream, with it's respective clocks incoming @ IN0 that is slaved to BCLK1/LRCLK1.

    Similarly I've got 4 I2S data streams being output on OUT0-3. I have the same BCLK and LRCLK that the input I2S data stream is clocked to, connected…

  • ADAU1442/ADAU1445 ASRC performance

    Is any performance or implementation data available for the ASRCs on these SigmaDSP parts such as THD, DNR, or FIR taps/group delay?  If not, I notice the supported ratios match the AD1895/AD1896---is it reasonable to use, say, the AD1895 as a proxy?  Since…

  • ADAU1445 FIR filter MIPS calculation

    Hi,

    We are using the ADAU1445 for FIR processing. Recently we have updated Sigma Studio (now using 3.11 Build 2, Rev. 1396) and noticed the following entry in the compiler output:

    Obsolete algorithm code encountered in this project:

  • ADAU1445 one output channel missing

    Hi,

    I've enclosed my project for somebody who can take a look and maybe help me:)

    The problem is that I cannot get signal on output channel no 0,2,4,6. When I put a level indicator on one of this channel on the schematic it shows that there is signal…

  • ADAU1445: Adress inputs not working

    In my device I used four ADAU 1445. IC's are adressed by inputs ADDR0 and ADDR1. CLATCH is tied to GND. Still, all ciucuits are adress 70, instead respectively 70,72,74,76.

  • ADAU1445/1446 flexible routing matrix

    Hello to all,

    in my design i have a ADAU1442 and up to 3 AD1938 can be connected. I have to design a multiroom application and want to equalize every Output channel. I make a design to switch every input channel to every output channel. I used the MUX…

  • Distortion with ASRC input on ADAU1445

    I am experiencing noticeable distortion when using an synchronous input on the 1445. I used a logic analyzer to capture the samples going to the 1445 and verified that they are pure (I'm using a canned 1kHz digital tone in the processor feeding the asynchronous…

  • How many possible instructions ADAU1445/1446

    I am a little bit confused - the datasheet of the ADAU1445/46 clearly states that the core allows 3584 instructions @ 48 kHz.

    However when I read the "compiler_output.txt" file it mentions 4096 possible instructions. Is the difference of 512 instructions…

  • adau1445 serial output data width issue

    I have set adau1445 serial output line to TDM2 16bit 48Khz slave mode, and inside DSP, I'm using a Tone (Lookup/sine) block to generate 2Khz sine wave to the serial output line. From what I've probed, the serial output data is always 24 bits, i.e. the…

  • ADAU1445 - no signal on SDATA_OUT0 when used as slave

    In a dedicated prototype, I use an ADAU1445 to re-sample 16 input channels. I use 2x TDM8 as input and 2x TDM8 as output. BCLK and LRCLK are both slave(input/output), applying 48k on LRCLK0/LRCLK9 and 12.288MHz on BCLK0/BCLK9 (from 2 different clock domains…
