Introduction
Digital inputs to the DAC can be provided with CMOS level signals up to 275 MSPS through 80-pin
headers. Doing so enables the user to provide high-speed digital data to the DAC5652A.
The analog output from the DAC is available via SMA connectors. Because of its flexible design the
analog output of the DAC5652A can be configured to drive a 50-
Ω
terminated cable using a 4:1 or 1:1
impedance ratio transformer or single-ended referred to GND.
Power connections to the EVM are via banana jack sockets. Separate sockets are provided for the analog
and digital supplies.
In addition to the internal band-gap reference provided by the DAC5652A device, options are provided on
the EVM to allow external reference to be provided to the DAC.
