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:
GND ————————- GND
VDD (5V) ——————- VCC
VO ————————– NC (empty)
RS ————————– NC (empty)
R / W ————————- MUXOUT
EN ————————– CLK
DB0 ————————- DATA
DB1 ————————- LE
DB2 ————————- CE (has 10K pullup)
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.

Package Included:
1 x RF Signal Source Frequency Synthesizer
