7.3.5 Digital Interface

The serial LVDS interface supports the data output with 2-wire, 1-wire and 1/2-wire operation. The actual data output rate depends on the output resolution and number of lanes used.

The ADC3683-SP requires an external serial LVDS clock input (DCLKIN), which is used to transmit the data out of the ADC along with the data clock (DCLK). The phase relationship between DCLKIN and the sampling clock must meet requirements in the timing diagrams in Section 6. The SLVDS interface is configured using SPI register writes.
