General Description
The CDB5530U is an inexpensive tool designed to eval-
uate the functionality and performance of the CS5530.
The CS5530 data sheet should be read and consulted
when using the CDB5530U evaluation board.
The evaluation board includes a C8051F320 microcon-
troller with a USB interface. The microcontroller controls
the serial communication between the evaluation board
and the PC via the firmware, enabling quick and easy ac-
cess to all of the CS5530’s registers and functions.
The CDB5530U includes software for Data Capture,
Time Domain Analysis, Histogram Analysis, and Fre-
quency Domain Analysis.

... Evaluation Board Overview The CDB5530U evaluation board is partitioned into two main sections — analog and digital. The analog section consists of the CS5530 and a precision voltage reference. The digital section consists of the mi- crocontroller, the reset circuitry, and the USB interface. The board also has power supply connections which accommodate all of the various supply options of the CS5530. The evaluation board’ ...

... Note that the VA- supply should be connected to ground when powering the CDB5530U from a single +5 V analog supply. VD+ supplies the digital section of the ADC and level shifters. Header J15 allows the VD+ supply to be sourced from the VD+ binding post (J5), the +5 V binding post (J3), or the regulated +3.3 V supply derived from the microcontroller. The +5 V bind- ing post supplies the microcontroller’ ...

... The user has two options for the data source: USB and File. If the USB setup is selected, the evaluation software will be ready to communicate with the CDB5530U via the USB connection. At this point, the Part menu item is active and the appropriate CS5530U device can be selected. If the File source is selected, the evaluation software will prompt the user to select the appropriate data file ...
