I need to clock several AD9613 ADCs simultaneously, with a configurable clock.
I've thought about using an oscillator to as input the ADF4350/1 PLL to generate the clock, then distribute it to all ADCs via the ADCLK846.
I have some questions about this:
Do you need LVDS outputs? Typically ADCs benefit from the large swing and fast slew rate of an LVPECL driver.
This circuit note shows an ADF4351 connected to the ADCLK948 and the resulting performance.
There is a 1:6 LVPECL buffer similar to the ADCLK846 called the ADCLK946.
If an LVDS buffer is required, you will have to be cautious to meet the input common mode and allowable swing. Since the LVDS buffers are on a 1.8V supply, they cannot handle as large of a swing as the LVPECL buffers.
Let me know if I can help further.
