      • Digital audio transfer between two Si4721 EVB

        Recep Onur Yıldız | 12/347/2018 | 05:31 AM

        Hello,

        I have two Si47xx baseboards and two Si4721 daughterboards. I want to operate Si471 boards as in digital audio mode. One operates in receiver mode and the other operates in transmitter mode. By default of baseboards configuration, digital audio transforms into analog audio by audio codec. But,  what i want to do is connecting receviver's digital audio output lines to transmitter's digital audio input lines. Is there any instructions about what to do, which pin to connect or hardware changes?

        Best regards.

      • SI4730-D60-GM unused pins

        Jaakko Niemi | 10/302/2018 | 11:38 AM

        Hi,

        We are using AM/FM Receiver Si4730 in our design. We use only FM receiver and analog output mode. Control interface is I2C bus. What is the correct way to connect the unused pins (AMI, DOUT, GPO1 and DFS)? Below is a picture of the connections at the moment.

      • Si4713+I2S reference clock generation from DCLK

        Recep Onur Yıldız | 09/262/2018 | 10:24 AM

        Hello,

        I am using si4713 with custom board. The board is working good in analog audio input mode. What i want to do is operating si4713 in digital audio input mode. So, i change the layout in my board according to the datasheet. Also, i changed some of the registers' value. The frequency of DCLK is 2.84 MHz and the frequency of REFCLK_FREQ = 32.768 kHz.

        • Power up command's ARG1 = 0x02      ARG2 = 0x0F
        • REFCLK_PRESCALE value is 0x1056
        • DIGITAL_INPUT_SAMPLE_RATE value is 0xBB80
        • DIGITAL_INPUT_FORMAT value 0x0002

        I am trying to generate REFCLK from DCLK. I measure the DCLK pin and it has 3.5 Vpp with 1.75V offset and the frequency of square wave is 2.84 MHz. Do you have any idea?

        Best Regards,

        Recep Onur
