TAS2553 Evaluation Module

Meria Jacob
Intellectual 370 points
Other Parts Discussed in Thread: TAS2553, TAS2552

Hi,

 

We are planning to use the audio codec TAS2553 in our end design.

We would like to know if you have any EVM available for TAS2553 to be interfaced with i.Mx7 Dual. Please share the full part number of the evaluation module of TAS2553.

 

We want the EVM to be interfaced with SABRE and WARP7 Boards. Please let us know if  the EVM can be directly interfaced with SABRE and WARP7 boards? If not,  please share if you have any interface boards available? Please share the relevant documentation and supporting documents for the same.

 

Thanks,
regards,

Meria Jacob

    Hi Meria,

    I am moving your post from Medical Forum to Audio Amplifiers forum where the device is supported.

    Hi Meria,

    I have replied to your post in the Audio Converters forum:
    TAS2553 have digital interface that can be configured to I2S, LJF, RJF, DSP and PDM modes, in addition, this device is able to use an analog differential mono input.
    If i.Mx7 supports these audio interfaces then the EVM can be connected to this board. I think i.Mx7 supports I2S.
    TAS2553 does not have EVM board but there is the TAS2552 EVM board, that is pin to pin compatible. You could use this board for evaluation.

    Hi,

    Thanks for the information.

    Could you please give the details of the connector  in TAS2552EVM from which we could tape the I2S and I2C signals for the evaluation purpose? I guess its J1 and J2 for SCL and SDA.

    Also, if you could give the details of the mating connector, it would be helpful for us.

    Also, in the TAS2552EVM, while connecting to SABRE Board, which all supplies should we give for the I2C and I2S communication. I got confused with 4 supplies. Our intention is to connect the I2C  and I2S signals from EVM -->>> Interface Board-->> SABRE i.Mx7

    For this to work, what all settings to be done?

    Thanks,
    Regards,

    Hi Meria,

    As you said, for external I2C interface SCL is connected to J1 and SDA to J2. You must remove JP1 and JP2.
    For the I2S interface you must remove all jumpers on JP3 except SCL, SDA and A0. DATA (DIN), MCLK, BCLK and WCLK (LRCLK) must be connected to the pin in the middle of the pin connector and GND on the right of the pin connector.
    The connector we usually use is a dual square pin female connector.
    You must configure the device to use digital I2S interface. TAS2552 will be slave device? Do you know the clock frequencies? Sampling frequency?
    I don't completely understand your question about the 4 supplies. Could you explain a bit more?

    Hi,

    Thank you for the reply.

    My requirement is to connect this evaluation module to the SABRE i.Mx7 from NXP. The SABRE Board have a I2C and I2S interface (CS, CLK,MISO,MOSI). At present  we have interfaced only LRCLK,DIN,DOUT,SDA,SCL,BCLK signals from the evaluation board to the interface board and then to the SABERE Board.

    While interfacing, do we need to provide any voltage supply to the evaluation module or these signals, LRCLK,DIN,DOUT,SDA,SCL,BCLK would be fine?

    Also, do we need to connect A0 , EN ,MCLK and IVCLK to our interface board? Are these signals required ?

    Kindly guide me in this regard..

    Thanks,

    Regards,

    Meria Jacob

    Yes. TA522 is a slave device. i.Mx7 is the master device. While using the I2S interface do we need to use the MCLK also? Or LRCLK,DIN,DOUT,BCLK is enough?

    Meria,

    Digital interface signals should be enough (LRCLK, DIN, DOUT, BCLK, SDA, SCL) as long as the devices share the same digital voltage thresholds.
    A0 and EN don't need to be connected to the host, you should use the jumpers as specified in the user's guide for these two pins.
    MCLK could be used or not, you can use a different clock input for the internal clock tree. This is configured into the TAS2552 registers.
    IVCLK is used if you need I/V data for external processing. If you won't use the I/V sense data then this is not required.

    Also, this audio codec is tolerant up-to to 3.6V right ? Including Digital interface signals LRCLK, DIN, DOUT, BCLK, SDA, SCL.

    Meria,

    IOVDD can be supplied by voltages between 1.5V and 3.6V and the digital input/output voltage levels are set according to IOVDD, so the digital interface signals are tolerant up to 3.6V. Only the AVDD voltage supply should not go over 1.95V.

    Hi,

    While powering up we need to connect only the external +5V  and GND to the pins rights? No other power supply is required , I guess. Kindly confirm.

    Also, there is a query regarding the JP3 Connector. In the datsheet the pin numbering is 1,2,3. But in the evaluation module slikscreen, it is mentioned 1,11,21. Kindly confirm.

    The footprint of the connector in our board.

    We are proceeding as per the connector datasheet.TSW-110-08-T-T. So we have placed the mating connector ESQ-110-12-G-T in our baord. For both these connectors the pin numering pattern is same. ie 1,2,3in one coloumn

    TSW-110-08-T-T HEADER,THU,30P,3X10,MALE,TRIPLE ROW,100LS,200TL Samtec ESQ-110-12-G-T Samtec

    Kindly confirm the same.

    Thanks,

    Regards,

    Hi Meria,

    Regarding the power supply, you need +5V and the VBAT supply. VBAT supply can go from 3.0 to 5.5 V.
    The +5V can be connected with an external supply or through the USB connection. There is more detail in the User's Guide.
    Regarding the connector, it is used to select between an external source for the digital input interface or the digital interface onboard. The detailed connection is shown in the user's guide schematic.

    Hi Meria,

    I'm not sure why is there a difference on the pin numbering of the JP3 connector. However you should follow the connections used in the EVM board for a good communication, ie first column for LRCLK, second column for BCLK and so on.
