AD9364 configuration procedure

Dear Sir,

We want to use the AD9364 RF transceiver as a GPS receiver. 

Right now we are using the AD-FMCOMMS4-EBZ, and as a starting point, we have successfully made it work with the SCOPE example. But in our target application, we have to (FPGA size restrictions) implement a fully FPGA GPS embedded design so there is no room to include your complete Linux/No-OS drivers and HDL IP-CORES. 

 

We are going to use the AD9364 in a very basic way, just 4 "commands":

  1. TX switched off (no need to transmit at all)
  2. RX internal LO tunned to a single frequency 1575.42 MHz.
  3. Fixed sampling frequency 50MHz
  4. Automatic gain control enabled

 

So we would like to know which is the minimal set of registers to achieve the afore-mentioned 4 "commands". We know you have to program via SPI, and we do have an IP-CORE to program via SPI. Of at least some guidelines to "digest" the drivers source code. For example any kind of flowcharts, etc...

 

Sincerely

 

Orlando Peña
