Based on the technology of the pixel detector (PXD) at the Belle II experiment @KEK/Japan a
direct electron detector system was developed for time-resolved imaging applications. It consists of
four two-side buttable all silicon modules (512x512 pixels each) capable to capture full frame
images in a burst mode with up to 100 pictures @80k frame rate.
To realize the necessary 26Mbit memory for the local frame storage array and the sequencer
memories under the tight space conditions a TSMC 40nm technology was chosen.
To send out the captured picture data sets to the following DAQ, up to 8 middle speed serial links
and a cross bar switch like routing structure are implemented.
Selected sub-circuits, as the PLL, a fine grained delay unit and the SRAM IP integration were
already successfully verified with a test chip manufactured via an Europractice miniasic run in the
same technology.
The DMC is fully controllable via a standard JTAG interface, where all configuration registers are
implemented as JTAG chain extensions and well described in a standard conform extended
Boundary Scan Description Language (BDSL) file. The python based test-bench preparation
includes serial vector file (SVF) format generation based on this BSDL file and a small sequencer
compiler. With these a digital full system verification of the all silicon module was performed to
check the system behavior before the final submission.
