6.3.6 JESD204B Interface

The ADC34RF5x uses the JESD204B high-speed serial interface to transfer data from the ADC to the receiving logic device. ADC34RF5x serialized lanes are capable of operating up to 13 Gbps, slightly above the JESD204B max lane rate. A maximum of 8 lanes can be used to allow lower lane rates for interfacing with speed limited logic devices. Figure 6-41 shows a simplified block diagram of the JESD204B interface.
