The oscillator is designed to be used as RF generator from 0 to 40Mhz or as a VFO for a transceiver taking into account the conversion of IF and offset SSB or CW. AA7EJ Ham Member QRZ Page. The clock value is to be set in resulting value (multiplication by 6 must be included in case of AD9851). Генератор синусоидальных и прямоугольных сигналов с максимальной частотой тактового сигнала 180 МГц, имеет регулятор частоты и фазы, собран на микросхеме ad9851. The value is set in hexadecimal notation, as usual. Disposant d'un générateur DDS AD9851 issu d'un ancien kit de F1BBU et piloté par un PIC 16F628 préprogrammé, l'idée m'est venue de le transformer en VFO avec le DDS piloté cette fois par une platine à microcontrôleur "Arduino Uno".
