AD-FRQCVT1-EBZ Functional Overview
The AD-FRQCVT1 extends the frequency of operation for the AD-FMCOMMS2/3/4:
- 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.
Control/Monitor
Power
Key components:
| ADP2370 | Buck regulator, 800mA, 3.2 to 15V |
| ADM7154 | Low dropout, linear regulator, 600mA, 2.3 to 5.5V |
| ADP7104 | High accuracy, 500mA LDO |
