The device clock inputs must be AC-coupled to the device to provide the rated performance. The clock source must have low jitter (integrated phase noise) for the ADC to meet the stated SNR performance, especially when operating at higher input frequencies. The clock signal can be filtered with a band pass filter to remove some of the broad band clock noise. In multi-channel systems the SYSREF signal can be generated using a LMK04828 or LMK04832 device. The LMK device can also be used as a system clock synthesizer.
