NEW AD9851 DDS Function Signal Generator 0 - 50MHz DDS Source SCM + DDS Module

NEW AD9851 DDS Function Signal Generator 0 - 50MHz DDS Source SCM + DDS Module

Description:
AD9851 uses advanced DDS technology, direct frequency synthesis, can produce spectrally pure, frequency and phase can be, programming control and stability of a good sine wave. Increased relative to the AD9850 internal multiplier 6, the reference clock just 30MHZ, 180MHZ, they would get the system clock. Design output 0 ~ 70MHZ, effectively reducing the external frequency source phase noise generated.

AD9851 Functional Description:
- Using AD9851 DDS chip, the external clock is active 30MHZ crystal.
- Using seventh-order elliptic filter, cutoff frequency 70MHZ, step 0.04HZ; phase 16, step 11.25.
- Sinusoidal output signal, square wave signal, amplitude stability.
- 50% duty cycle square Bomo recognized.

1, the product design frequency range of 0 ~ 50MHz, step 1Hz, frequency output stable.
Remark:Sine wave: 0Hz-50MHz, Square wave 0Hz-5MHz，more than 1MHz, the amplitude fading As The Frequency Increases
- Output waveform: sine wave, square wave.
- Output signal amplitude stability: 1Vp-p.
- Output frequency control: Four keys to operate independently, simple and quick.

2, this design can be disassembled into separate modules and AD9851 51 experimental test module
- LCD removed, then the short circuit between the AD9851 AT89S52 and remove the child, the circuit board on the left is the independent board of 51 single-chip experiment (with SPI download port), the circuit board on the right is independent of the AD9851 experiment board.
- Output interface: signal generator dedicated connector, and a complimentary special signal generator output line.

Package List:
- 1 * DDS signal generator
