Page 2: Introduction
The ADC36xxEVM is an evaluation board used to evaluate the ADC368x analog-to-digital converters (ADC) from Texas Instruments. The ADC368x uses a serial LVDS interface to output the digital data. The serialized LVDS interface supports output rates to 1 Gbps. The ADC368x can be operated in 'oversampling + decimating' mode using the internal decimation filter in order to improve the dynamic range and relax external anti-aliasing filter. - Page 3 Equipment Figure 2-1.
