ADAU146x SRC Latency
Hello, I've got an ADAU1462 project that takes i2s in, sends through ASRC to internal sample rate of 96kHz. When measuring the end-to-end latency of the system with fs_in = 48kHz, I get 1.521ms, and w

ADAU14: Capturing pulse shorter than a frame?
Using ADAU1462 will it be possible to capture pulses shorter than an audio frame? E.g. can in inputs be set as rising edge triggered so it remembers the state even though the signal is no longer high

Sigma studio coeff calculation filter broken
When I try to use a coefficient calculation filter, it turns my sine tone test signal into a square wave (output of DAC). When I replace it with a general 2nd order block with the same parameters, it

Format of inputs and outputs
Hi, On the board we use a Delta-Sigma encoder/decoder (CS42488). Can we use directly this format in the DSP? or do we have to do some Delta-Sigma to uniform conversion before ? Thanks for your help, I

PLL_CTRL0 editing should happen before PLL_ENABLE changes from 0 to 1, but sigmastudio generates code where PLL_CTRL0 is edited after PLL_ENABLE is changed from 0 to 1
Hello We have a project utilizing the ADAU1462 and have noticed the file generation for the function "default_download_xx" where xx depends on the project name, might be wrong according to what is spe

Output delay and other timing specs of ADAU146x audio serial ports (and SPI)
Hi, I'm trying to cross-check the timings of various high-speed signals (SPI and audio TDM) between chips that are interfaced on our board, specifically the ADAU146x, AD2428, and our host SoC (TI AM33

ADAU146X - Low-Power Mode and Wake up from digital audio signal
Hello, I am trying to figure out a standby/sleep scheeme for a DSP/amplifier board featuring the ADAU1462/66. To wake up the board via my ADC its pretty clear, since it has a threshold based audio det

Sending I2S from DSP to external DACs
Hi, I am trying to send I2S signal from DSP to external PCM1794 DACs. MCLK is sent out correctly from CLKOUT at 24.576MHz, but nothing else is getting out from serial outputs. What am I missing? Signa

Can SigmaStudio realize dynamic allocation of resource?
I am using ADAU1467 to make a AMP project. supply 32 outputs, and each output implements 31-segment EQ and 48DB/OCT high-pass/low-pass, which exceeds MIPS of ADAU1462. Can SigmaStudio realize dynamic

ADAU1462 TDM16 Serial IO Not Working
I'm currently trying to program the ADAU1642 and I'm having issues with both reading TDM16 signals in and writing it out at 44.1kHz with 32 bits per channel. I saw a similar post made about the ADAU16

Master Control Port XML works in realtime link-compiling but not after boot
Hi, I need a help with my SS project: I'm using a Master Control Port Boot to write some register configuration to my ADC and DACs When I use it in realtime link-compile-download, works very well, but

Is it possible to program the ADAU1462 without an EEPROM?
I'm getting started designing a board with the ADAU1462 and I'd like to avoid adding an EEPROM on board if possible and instead opt to program it from the microprocessor that acts as its I2C controlle

USB communication failure on filter parameter-change
Hi! I have a strange problem with my ADAU1462 based custom HW: The situation is: I'm well connected to the HW through USBi (SPI), .dspproj is "link compile download" and the connection status is "Acti

Interchangeability of ADAU1452/1451/1450 and ADAU1462/1466
Hello, As said in ADAU1462/1466 datasheet, it seems to be compatible pin to pin and in registers to the ADAU1452/1451/1450. I would like to know if this is really true and (with a reduced signal proce

Cannot find the ADAU1462-150 in the part library list
Hi Dave, I used the default settings for adau1462-150 but it didn't work. I can only see the MCLK output but nothing else happened. I just dragged adau1462 from the processor list and put the input/ou

Are these DSP's best for this kind of Active noise cancellation for rigid barriers?
Me and my partner have been looking at many of your DSP's Eval boards to use for our Active Noise Cancelation (ANC) Senior design project. We are trying to stay under $250, just for the DSP Eval board
