Dear support team,
We are currently using a Si4685 FM / AM DAB receiver with the following firmware versions (which we got some time ago from Silicon Labs):
How can we get the current Firmware and documentation?
I am trying to control Si4721-EVB with Audio GUI software. The initialization window is attached. I tried to program daughter board as in both transmitter and receiver mode. But every single time i got the error. The error message is also attached. Are there any possible solutions?
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?
We have to a Si1707-B-EVB (evaluation board) into the CD find Si473x-EVB documentation with 1.4 revision.
But in the daughtercard silkscreen appear 1.5 revision.
Someone have the 1.5 documentation?
Thanks in advance!
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.

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.
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?
