In addition, with 1/2/4/8/16/32/64 crossover circuits, users can generate RF output frequencies as low as 35 MHz. For applications requiring isolation, the RF output stage can be muted. The mute function can be controlled by pins or software. At the same time provide auxiliary RF output, and can be turned off when not in use.
Precautions for using the module(1) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply.(2) Correct power supply, reverse connection is prohibited, and the voltage should not exceed 5.5V.(3) It is recommended to use a good patch cord to connect the instrument to observe the output signal. Poor contact or poor quality wires may cause signal attenuation or excessive noise.(4) If you need to simply test the function of the module, it is recommended to use it with the control board of our store. Power is supplied to the PLL module first, and then the power is supplied to the control board to generate a waveform. Long press the middle button to switch the function.(5) The distributed code is only used for the supporting main control board, and does not provide a single-chip microcomputer tutorial. Additional functions need to be developed by themselves.(6) The phase noise, harmonics, power output and other corresponding indicators of the phase-locked loop module. The typical test parameters are included in the details.
Frequently asked questionsQ: Is the output waveform of AD4351 not a sine wave, and the harmonics are very large?A: ADF4351 is a digital phase-locked loop. The frequency output below 2.2G is divided frequency output, the output waveform is similar to square wave, if you need a sine wave, you need an external filter.Q: Can the fastest sweep speed of ADF4351 be only 1mS? Can the minimum step be only 0.1MHz?A: The current loop bandwidth design and software design on the board, in order to support 35M-4.4G frequency can be output normally, so the minimum step and the fastest sweep time are fixed, and it is necessary to pursue smaller steps and faster sweep Time will require buyers to make hardware and software adjustments.Q: What are the two lights on the board for the phase-locked loop module, but it doesn't light up after importing the program?A: One is the power indication, the other is the lock indication, and both lights are on for normal operation. Generally, you need to power on the module first, and then power on the main control board. The power port on the main control board, the lock light is always on, and the module is normal output.
