1 Introduction

The ADC3660EVM is an evaluation board used to evaluate the ADC3660 analog-to-digital converter (ADC) from Texas Instruments. The ADC3660EVM is a dual-channel, 14-bit ADC that can operate up to 65 Mega-samples per second (MSPS). The ADC3660 uses a serial CMOS (SCMOS) interface to output the data. The serialized CMOS interface supports output rates to 250 Mbps which translates to ~ 15 MSPS (2-wire) to ~ 3.75 MSPS (0.5-wire) output rates after complex decimation. Hence the ADC3660 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 ADC3660EVM 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
  • FMC connector
  • CDCE6214 clocking solution for on-board clocking
