説明
The 84330B-03 is a general purpose, dual output high frequency synthesizer. The VCO operates at a frequency range of 250MHz to 700MHz. The VCO and output frequency can be programmed using the I2C interface. The output can be configured to divide the VCO frequency by 1, 2, 3, 4, and 6. Additionally, the device supports spread spectrum clocking (SSC) for minimizing Electromagnetic Interference (EMI). The low cycle-cycle jitter and broad frequency range of the 84330B-03 make it an ideal clock generator for a variety of demanding applications which require high performance.
