EVM Basic Function
1-3
Overview
1.2
EVM Basic Function
Analog inputs to the ADC are provided via six external SMB connectors. Two
pairs of SMB connectors provide true differential inputs, or two individual SMB
connectors provide single-ended transformer-coupled signals to the inputs of
the device.
The EVM provides an external SMB connection for input of the ADC clock. A
crystal oscillator is provided on the board to perform this function and can be
used when required. Refer to the section on clocking for correct provisioning.
Digital output from the EVM is via two 25-pin connectors. The digital lines from
the ADC are buffered before going to the connectors. More information on
these connectors can be found in the ADC output section.
Analog output from the EVM is via two SMB connectors (J1 and J3). A pair of
THS5651 10-bit DACS are used to recreate the analog signal from the ADC’s
digital data. More information on this can be found in the ADC analog output
section.
Power connections to the EVM are via a pair of screw-down connectors.
Separate input connectors are provided for the analog and digital supplies.
1.3
Power Requirements
The EVM is powered directly through independent 3.3-V analog and digital
supplies.
1.3.1
Voltage Limits
Exceeding the 3.3-V maximum can damage EVM components. Under voltage
may cause improper operation of some or all of the EVM components.
