1 Introduction

The ADC3664EVM is an evaluation board used to evaluate the ADC3664 analog-to-digital converter (ADC) from Texas Instruments. The ADC3664EVM is a dual-channel, 14-bit ADC that can operate up to 125 Mega-samples per second (MSPS). The ADC3664 uses a serial LVDS (SLVDS) interface to output the digital data. The SLVDS interface supports output rates to ~1 Gbps. The ADC3664 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.

The ADC3664EVM is equipped with the following features:

  • Transformer and FDA coupled analog inputs
  • Transformer coupled or single-ended clock inputs
  • INA226 current shunt monitors for evaluating power consumption

  • Power over mini-USB

  • FMC connector

By default, the EVM is configured to receive external inputs for the sampling clock and analog input via AC-coupled, transformer (balun) inputs. These transformers perform single-ended to differential conversion, and provide a low noise/distortion passive input.

To exercise the full performance capabilities of this high performance SAR ADC, it is recommended to evaluate the ADC in the default configuration, and then evaluate in other configurations (like utilizing the FDA input), as required.
