Hi
I need info which IC at the EX scanner mainboard is responsible for DSP and which for DDC (Digital Down Conversion): figure-3 in the SeeGull EX Hardware Reference Manual_Rel.3.0.
41871
For EX_WCDMA+GSM:I think that Xilinx Spartan-3 FPGA (IC=U17) is responsible for DDC. For DSP may be some of the ICs with heatsinks (U2, U4; don't know type). See attached picture:
41872
For EX_LTE: Please share your knowledge and pictures of EX-LTE (or EX-mini-LTE) mainboard. Is there Xilinx Spartan-3 FPGA or other type FPGA?
Thanks.
