I just purchased the Silcon Labs SI4735-D60-EVB EVALUATION Board for the SI4735 from Symmetry Electronics. I will be using the SI4735-D60-EVB mainly for flashing the Si4735.
I will be making my own breakout board and would like a wiring diagram for the "Si4735 Daughter Board".
If you have a link to the Si4735 daughter board wiring diagram it would be greatly appreciated.

Please see attached schematic of Si473x_D60 daughter.
You need to do following wiring:
1, VDD and VIO(usually they are 3.3VDC), and they can be combined into one;
2, RSTB and SENB;
3, I2C including SCLK and SDIO;
4, There is a crystal of 32.768KHz on the daughter card, so you don't need to provide RCLK signal, just connect J27 and J28;
4, Audio outputs of ROUT and LOUT.
