Product Usage:
ADF4351 development board refer to the official circuit schematic design, output frequency range: 35M-4.4G (ADF4351)

Technical Parameters:
1 .Output frequency range: 35MHz-4.4GHz (ADF4351)
2. Supply voltage: 4-9V (5VDC)
3. Output signal: 2.2GHZ-4.4GHz sine wave (fundamental)
35MHZ-2.2GHz (ADF4351)square wave (fundamental division)
4. Output signal: output speed, signal strength:+5dBm (programmable)
5. RF connector: SMA female head
6. Control Interface: Three-wire SPI
7. Reference Clock: 10.000MHZ (default), through the interface to an external SMA
8. PCB Size: 49x48x2mm; Connector protruding length: 10mm

Connection:
The module can pin microcontroller LCD1602 / LCD12864 module connection (can be plugged directly Backward), convenient software debugging, both lock indicator (Lock). Pin correspond to the following:

LCD1602 / LCD12864 ADF4350 / ADF4351
1.GND---------GND
2.VDD (5V)---------VCC
3.VO---------NC (empty)
4.RS---------NC (empty)
5.R/W---------MUXOUT
6.EN---------CLK
7.DB0---------DATA
8.DB1---------LE
9.DB2---------CE (has 10K pullup)
10.DB3---------GND (do not take)

Reference Clock:
10.000MHZ default reference clock signal is active clock or an external reference clock signal, you need to modify the three-way connection with a soldering iron, connect EXT REF external reference signal.

RF output:
For ease of use, the default is broadband output, the output of two differential signals, one way can be used to output use, the other way can be used to monitor the output.

Pakcage included:
1x ADF4351 PLL Frequency Synthesizer
