AD9850 0-55MHz Frequency LCD DDS Signal Generator Digital Module

AD9850 0-55MHz Frequency LCD DDS Signal Generator Digital Module Description

1. Supports 0-55MHz continual adjust at 1Hz step.
2. This generator has 78L05 voltage regulate. Input current at 200MA, input voltage 8-9V would be the ideal voltage.
3. Input voltage of 12V can only be used for short time testing, otherwise cause heat to board.
4. 5p/6p connect to encoder as per photo. 7p of the middle connects to digital matrix input. 14p (8V GND) is 8V power supply from main board.
5. If powered by main board, DDS does not need power supply.

1-6 correspond to 6 frequency bands: (3.8, 7, 9, 14, 18 or 21, 27 or 29).
, USB, CW are the three mode choices.
DT is signal from main board.
Keys and Connection interfaces:
ENC: Encoder switch
: Switch for memory mode
VFO: Transfer from VFO A to VFO B, or from VFO B to VFO A.
SSB: Working mode change: circulate from USB, LSB, AM, CW, and on and on...
: Fine tuning to receiving frequency
