Transmission Specifications
The AD-FRQCVT1-EBZ extends the frequency of operation for the FMCOMMS3/4/5:
Input signals in the frequency range of 1-100 MHz is up-converted to an output signal centered around 340 MHz to the AD-FMCOMMS board;
A output signal in the range of 1 to 100 MHz is generated by down-converting a 370 MHz signal from the AD-FMCOMMS board;
On-board programmable Phase-locked Loops frequency synthesizers generate the needed Local Oscillator signals used by the up- and down-converting mixers.

LO
The LO used in on this board is the ADF4351 which is software programmable. Please refer to the device data sheet for the two LO within this board. The board provides a 25MHz crystal for the ADF4351.
SPI
The SPI signals are directly passed to the FMC connector.
All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
