ADC Clock Source Configuration
The AFE clock input can be driven differentially (sine wave, LVPECL, or LVDS) or single-ended
(LVCMOS). The clock input of the device has an internal buffer and clock amplifier which is enabled or
disabled automatically, depending on the type of clock provided (auto-detect feature). Therefore, the EVM
allows for multiple clocking options.
