Page 3: Introduction
Introduction The GPX2-EVA-KIT evaluation system is designed as a platform for a quick and easy start of evaluation of the TDC-GPX2 time-to-digital converter. The kit offers a graphical user interface for user-friendly configuration and extensive testing of the TDC-GPX2. For a proper use of the evaluation system, we strongly recommended to refer to the latest TDC-GPX2 datasheet. -
Page 4: Quick Start Guide
TDC-GPX2 Standard Board Quick Start Guide This section describes how to set up the GPX2-EVA-KIT, establish basic operation and make measurements quickly. Install the Software It is crucial to install the software before connecting the evaluation kit to your computer. A default driver loading of your OS may interfere with correct installation. -
Page 5: Software
TDC-GPX2 Standard Board Connect the power supply. Make sure it is set to 6 V supply voltage. The green LED on the evaluation kit should be on. Connect your signal source. Software Excecute the GPX2 Frontpanel software. The communication status should be green ... -

SPI interface and can use the same to read data. In addition, the FPGA manages the readout from the serial LVDS outputs of the TDC-GPX2. The SPI signals are available via additional pads [3]. A jumper selects the supply voltage as 3.0 V, 3.3 V or 3.6 V [4]. A separate jumper allows measuring the current into the TDC-GPX2 [5]. -

Page 8: Software Description
TDC-GPX2 Standard Board Software Description Main Window, REFCLK Page The software start with the following main window: Figure 4: GPX2 evaluation software main window The main menu offers the typical functions to load and save configurations, to run a measurement, to open the graph and register windows as well as a help. -
Page 9: Stop Page
TDC-GPX2 Standard Board The first page, “REFCLK”, allows to select the reference input as well as the definition of the LSB. REFCLK_DIVISIONS defines the LSB at the output interface as fraction of the reference clock period. The most convenient way is applying an LSB of 1ps by configuring REFCLK_DIVISIONS to the picosecond value of the reference clock period. -

TDC-GPX2 Standard Board Interface Page On this page the communication as well as the output data format is defined. In any case, on the evaluation kit all communication is done via the on-board FPGA. Figure 7: Kit Content ams Eval Kit Manual... -
Page 11: Avoiding Configuration Conflicts
TDC-GPX2 Standard Board Avoiding Configuration Conflicts Some combinations of parameter settings can prohibit operation or cause erroneous results. Some of these combinations are indicated with a red bar. User should avoid such configurations since the results may be difficult to interpret or faulty at all. -
Page 12: Register Content
TDC-GPX2 Standard Board Register Content A separate window shows the register content in the GUI and the TDC-GPX2. Separate pages display configuration data and result data. Changing the hexadecimal values will change the configuration in the GUI accordingly. With “Write Config” the updated configuration is downloaded into the chip. -
Page 13: Graph Window
TDC-GPX2 Standard Board Graph Window The graphical display allows to select which data shall be displayed. The shape of the individual curves can be modified individually. Move the mouse over the line symbol and press the right mouse button. A menu with many options will pop up. - Page 14 TDC-GPX2 Standard Board The text file can then be analized with a table calcluation program. Figure 12: Exported data format Known Errors Software Hang-up Once in a while, typically during tests in the temperature chamber, it may happen that the software hangs up. This is most likely to erroneous reading from the FIFO and related in the FPGA.
