Difference: V4, V5: optimizing the line, increase the synchronizing signal source (optional increasing terminal can use an external signal trigger FSK/BPSK/HOLD), increases the switching power, the large heat sink design; V4 is the serial interface to facilitate external MCU control, V5 is a USB interface, convenient notebook users; Special attention: Using the latest PC software control chip AD9854, with MCU can completely control the chip of AD9854 all register (especially in the method of bit control bit set), MCU and the pin can very intuitive, very convenient to experiment with different, and to test single tone, FSK, Ramped FSK, chirp, such as BPSK function, quick to master AD9854 application! Provide two sets of procedures: a set of major PC end to complete the frequency control word processing procedures, MCU complete data communication. Another set of procedures PC transmission parameters, mainly by the MCU to complete the processing of the frequency control word. One, module features: 1, the output of two groups of differential output (phase: 0, 180, 90 and 270), the frequency can be up to 100MHz sine wave signal and signal frequency, phase and amplitude were usable program control; while the output a set of square wave signal. 2, this board is a senior engineer design, the output signal is very beautiful, this chip circuit processing is not good will cause the output wave form a jagged, output signal jitter, distortion. PCB reference to the design of the original plant module. 3, this module materials exquisite, the power supply IC, greatly enhanced the stability and reliability of the module, and in the quantity of heat is greatly reduced and board design can achieve the cooling effect, can work stably for a long time in the working frequency of 100MHz; the use of the a lot of SMD capacitors, very helpful for good output waveform, for the requirements of power supply is reduced greatly, ordinary power can be used. 4, AD9854 all the control pins are connected to the MCU (AVR) I/O feet, you can complete control of the AD9854 chip. 5, the module with MCU control, through the serial port and PC communication or other MCU communication, to facilitate the control of the output wave type AD9854. 6, provide the PC control software, and provide VB source code (old version), learning VB is a very useful. 7, module size: 72mm*98mm 8, AD9854 chip can achieve all the functions of Tone FSK, Ramped, FSK Single, Chirp, BPSK; 9, provide the bottom of the AD9854 chip driver source program, can be very convenient to write AD9854DDS chip control program. Program list is as follows: Init_9854 void (void); AD9854_phase1_adjust void (int phase_value unsigned); AD9854_phase2_adjust void (int phase_value unsigned); AD9854_frequency1_tuning_word void (frequency_value double); AD9854_frequency2_tuning_word void (frequency_value double); AD9854_delta_frequency_word void (delta_frequency_value double); AD9854_update_clock void (long update_clock_value unsigned); AD9854_ramp_rate_clock void (long clock_value unsigned); AD9854_control_bit void (AD9854_bit control_bit_value struct); AD9854_I_gain void (int gain_value unsigned); AD9854_Q_gain void (int gain_value unsigned); AD9854_shaped_keying_ramp_rate void (char ramp_value unsigned); AD9854_QDAC void (int QDAC_value unsigned);   Application of module: 1, high accuracy, high stability, high frequency programmable signal source 2, special signal source; 3, use to do the study of high performance DDS module; Four, module performance parameters: 1, working voltage, current: 1A 5V 2, the highest output frequency: sine wave 100Mhz, square wave 10Mhz 3, frequency step: 0.1HZ 4, amplitude can be adjusted to control the accuracy of 12BIT can be adjusted.
