Page 4: Introduction
DRS4 Evaluation Board User’s Manual 1. Introduction The DRS4 chip, which has been designed at the Paul Scherrer Institute, Switzerland by Stefan Ritt and Roberto Dinapoli is a Switched Capacitor Array (SCA) capable of digitizing eight channels at sampling speeds up to 6 GSPS. This chip is available through the PSI technology transfer program for other institutes and organizations. -
Page 5: Firmware Description
Both the Windows and the Linux distribution contain a subdirectory “firmware” which contains the FPGA and Microcontroller firmware for the DRS4 Evaluation Board. The FPGA firmware is written in pure VHDL, thus making it easy to port it to other FPGA devices such ®... -
Page 6: While The Mapping Of The Status Registers Is Like This
CY7C68014A/* Remaining files are standard files from EZ-USB development The FPGA firmware implements a set of control and status registers, through which the DRS4 can be controlled and read out. The mapping of the control registers is as follows: Ofs. -
Page 7: Installation
DRS4 Evaluation Board User’s Manual All registers are implemented as 32-bit registers, so they can be mapped easily into some VME address space for example if one decides to build a VME board containing the DRS4. 2. Installation 2.1. Windows XP ®... - Page 8 DRS4 Evaluation Board User’s Manual Then you can select the installation directory: After the installer has finished, you can connect the DRS4 Evaluation Board to the Computer: Now you will see the “Found New Hardware” dialog: Where you can click “Install the software automatically” and then click “Next”.
- Page 9 And a new group in your Start Menu: Clicking on „DRS Command Line Interface“ will start a simple application which connects to the DRS4 Evaluation Board. If it finds the board, it displays the board serial number and the firmware revision as on the following screen shot: Now you are ready to issue your first command “info”...
- Page 10 You can select the trigger mode, trigger level and trigger source. On Rev. 1.1 of the DRS4 evaluation board, only CH1 can be selected as trigger source. You enable a channel by clicking on the number “1” to “4”. There are two cursors and a few utilities.

Page 11: Linux
If this package is present, you can change to the drs directory and issue a make: [/usr/local]$ cd drs-1.0 [/usr/local/drs-1.0]$ make g++ -g -O2 -Wall -Wuninitialized -fno-strict-aliasing -Iinclude -DOS_LINUX Please check for possible updates of this manual under http://drs.web.psi.ch/datasheets... - Page 12 -DHAVE_LIBUSB -c src/mxml.c . . . Now you can connect the DRS4 board to the PC. On systems where the “lsusb” tool is installed, one should be able to find the DRS4 evaluation board after connecting it with following command: [/usr/local/drs-1.0]$ /sbin/lsusb -d 04b4:1175 –v...

It will open a X window and show exactly the same functionality as its Windows counterpart: Please check for possible updates of this manual under http://drs.web.psi.ch/datasheets...

Page 14: Development Hints
DRS4 Evaluation Board User’s Manual 3. Development Hints The idea behind the evaluation board is to make first steps in using the DRS4 chip, but then develop your own custom electronics around the chip. The first thing to do there is to study carefully the DRS4 data sheet, which can be obtained from http://drs.web.psi.ch/datasheets. -
Page 15: Analog Input
750 MHz. The peaking can be reduced by adding a series resistor of a few Ohm between the buffer output and the DRS4 input. The usual design rules like proper termination and matched impedance PCB traces apply as in any high frequency analog design. -
