1 Introduction
1.1 EVM Block Diagram
Figure 1 shows a simplified block diagram of the default configuration of the EVM. The four analog inputs
are supplied to the EVM through a single-ended SMA connection, then transformer coupled, turning the
single-ended signal into a balanced differential signal, and then input to the ADS58H4x. A dual
transformer input circuit provides better phase and amplitude balance of the input signal when compared
to the performance delivered by a single transformer input circuit.
