Note that the Baluns on the Rev C board (T101-T104) are either:
- Johanson Technology's 2450BL15B050E 2.45 GHz Balun. This balun is rated for a operating frequency of 2400~2500 MHz and is connected to RXB Input and TXB Output. If you want to evaluate the part outside of this frequency range, use the other SMA.
- Mini Circuits TCM1-63AX+. They are rated for an operating frequency between 70 MHz and 6 GHz, and are connected to the RXA Input and TXB Output.

Note that the Baluns on the Rev B board (T101-T104) are either:
- Johanson Technology's 2450BL15B050E 2.45 GHz Balun. This balun is rated for a operating frequency of 2400~2500 MHz. If you want to evaluate the part outside of this frequency range, an alternative balun should be installed. The test results were taken using the Johanson Technology's 2450BL15B050E balun.
- Mini Circuits TCM1-63AX+. They are rated for an operating frequency between 10 MHz and 6 GHz.

- The Epson crystal used on this board, has the generic part number “TSX-3225 40.0000MHZ” - however, the generic part number does not have the specifications needed to meet the AD9361 datasheet specs. ADI has worked with Epson to provide a tighter tolerance part, which can be ordered as the “OUTD-2B-0166” or “X1E000021036701” (either part number will work, depending on which system your Epson contact/distributor has) which meets the requirements that the AD9361 demands.
I/O Voltage
The AD-FMComms4 (AD9364) assumes a VDD_INTERFACE voltage between 1.71V and 2.625V (1.8 to 2.5 +/- 5%), so on your FPGA carrier board, you should ensure that VADJ is between these levels. Setting things to 3.3V will damage the part.

Layers
The AD-FMCOMMS4-EBZ is a 10 layer board.
