SI4735 Daughter Board Wiring Diagram Needed

[ Edited ]

Hi 

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.

Re: SI4735 Daughter Board Wiring Diagram Needed

Hello,

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.
