TDM2 oder 8 channels
Hey together, one question. We know that it is possible to send 16 channels of audio via serial port 0/1 via a single SDATA pin (16 channels), via 2 SDATA pins (2x8channels) and 4 SDATA pins (4x4chann

ADAU1467 TDM16 problem
Hello, I'm working on a custom A2B subordinate board. The subordinate transceiver get 16 streams from A2B network and generates a TDM16 towards a ADAU1467 with the input serial port 1 configured like

Using ASRC and not getting audio output from analogue connector
Hi there, Sorry, I've browsed a couple of other solutions for "similar" problems to mine, but I can't seem to put my finger on why my system isn't working. I put together a test project (attached) to

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

ADAU1452 serial port is 16bit but calculations are 32bits
Hi, I am working with the ADAU1452 on the Sigma Studio 4.6, I stream to its serial input ports accelerometer data (3 axis of adxl317). The accelerometer is configured to output each channel as 16bit d

Process each channel in a TDM4 input stream
Hi, I stream TDM4 signal to ADAU1452 sigmaDSP through SDATA_IN0. I want to process each channel from this TDM4 signal (Filter and maybe more). How can I do it? When done processing each channel, I nee

ADAU1401A: can it use both TDM and I2S inputs?
Hello, I would like to know if I can configure the ADAU1401A to receive data from a 8-ch TDM stream (only 4 channels, at the left part) on SDATA_0 and 2 additional channels in I2S format on SDATA_1. I

ADAU1463 TDM16 in slave mode
Hello, We use the ADAU1463 in a system with TDM16 signal 24/32 bits on 48kHz on Serial Port 0 from a FPGA but the dsp is not working correct as slave from this input 0. Every time the systems starts t

3 x TDM8 inputs to ADAU1467
Hi there, I have a Multichannel USB streamer device that I wish to use to send 24 channels of digital audio to an ADAU1467, utilising 3 x TDM8 lines. Therefore, I am hoping to just use Serial Inputs 0

A commom audio transfer question in TDM16 format
Hi, I always meet with difficulty in several different projects. When I use TDM16 format to receive datas using ADAU1452, I can get all the 16 channels audio datas and it sounds like good. What confus

ADAU1467 TDM4 mode
Hi, my system consists of an ADAU1467 and two PCM3168A codecs, for a total of 8 inputs (4 on each codec) and 16 outputs (8 on each codec). DSP and CODECS receive both the master clock from a 24.576 MH

ADAU1701 and TI digital AMP rattling noise with LP-filtered signal
Hey folks, I´ve already done a project with the ADAU1452 and wanted to realize a small 4In4 DSP amplifer. Therefore I´ve moved to the ADAU1701 and a digital TDM input amp from TI TAS6424.

TDM of 2x2 stereo channels between 2 ADAU1467
We have problems using TDM where one of the ports is slave to another TDM port. Here is the case: We have to transfer 4 stereo channels using two ports, port 1 and port 3 between two ADAU1467. Sample

ADAU1452 drive strength and equivalent resistance or impedance
In the datasheet there is only information about maximum current versus drive strength setting, ie at 3.3V Lowest 2mA Low 5mA High 10mA Highest 15mA A simple calculation implies that the R-ON for the

ADAU1452 -> ADAU1462 ASRC and 192kHz SPDIF
I have a product that has been in the market for several years now using the ADAU1452. It's only limiting factor for us right now is that the SPDIF input on that part maxes out at 96khz and we have ma
