説明
The 8430-11 is a general purpose, dual output Crystal-to-3.3V Differential LVPECL High Frequency Synthesizer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The 8430-11 has a selectable crystal oscillator interface or LVCMOS TEST_CLK. The VCO operates at a frequency range of 200MHz to 700MHz. With the output configured to divide the VCO frequency by 2, output frequency steps as small as 2MHz can be achieved using a 16MHz crystal or reference clock. Output frequencies up to 700MHz can be programmed using the serial or parallel interfaces to the configuration logic. The low jitter and frequency range of the 8430-11 make it an ideal clock generator for most clock tree applications.
