Purpose
The THS1215/30 EVM provides a platform for evaluating the THS1215/30
analog-to-digital converter (ADC) under various signal, reference, and supply
conditions. The system block diagram is shown below. This illustration
provides a general indication of the features and functions available. It should
be used in combination with the circuit schematic supplied.

EVM Basic Functions
Analog input to the ADC is provided via two external SMA connectors. The
input can be configured onboard to be true differential, single-ended, or
single-ended transformer coupled to the device.
The EVM provides an external SMA connection for input of the ADC clock.
This can be configured to be either ac or dc-coupled. A crystal oscillator is
provided on the board to perform this function, and can be used when required.
Refer to the Internal Clock section for proper configuration and operation.
