AD9851 DDS Function Signal Generator 0 - 50MHz DDS signal source DDS Module AD9851 DDS Function Signal Generator 0 - 50MHz DDS signal source DDS Module Features: 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. * 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 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. Please note: Unit uses 80C55RC processor and has no memory function After power down returns to the default 100.000KHz frequency. Package included : 1 * DDS signal generator 1 * BNC Signal Cable SHIPPING All the items will be dispatched within 1 business day by Hong Kong Airmail after the payment is clear.
