THS3215EVM and THS3217EVM

This user guide describes the characteristics, operation, and use of the THS3215EVM and THS317EVM
(THS321xEVM). This evaluation module (EVM) is a demonstration fixture for the

THS3215

and

THS3217

family of wideband, differential DAC to single-ended line drivers. The EVM provides 50-

Ω

input and output

termination for easy evaluation with common 50-

Ω

test equipment. A complete circuit description,

schematic diagram, printed circuit board (PCB) layout, and bill of materials are included.

Throughout this document, the terms demonstration kit, evaluation board, evaluation module, and EVM
are synonymous with the THS321xEVM.
