Introduction

With proper hardware selection in the HSDC Pro software, the TSW14J56 device is automatically
configured to support a wide range of operating speeds of the ADC16DX370EVM, but it may not cover the
full operating range of the ADC device. Serial data rates (and corresponding sampling rates) of 7.4 Gb/s
(370 MSPS) down to 1.6 Gb/s (80 MSPS) are supported.

For the rest of this document, the ADC16DX370EVM evaluation board is referred to as EVM and the
ADC16DX370 device is referred to as ADC device.
