AIDA annual meeting,Vienna, 26th March 2014Václav Vrba, Institute of Physics, Prague 1 design of sensors for production submission design of the readout chain plans for near future

ON Semiconductor AIDA annual meeting,Vienna, 26th March 2014Václav Vrba, Institute of Physics, Prague 2 ON Semiconductor: 6” wafers stepping mask projection machines, the stitching technique is needed some problem inside ON Semi with man power to be dedicated to that task we are continuing the discussion with ON Semi, but no date fixed in meanwhile we are we are looking for other sensor providers we received few quotation, the price (confidential) significantly overrides our expectations despite of that we believe to come to the acceptable solution
3
Development of a full read out chain AIDA annual meeting,Vienna, 26th March 2014Václav Vrba, Institute of Physics, Prague 3 the chain was tested on the pixel sensor array with the RO MediPix chip but in principle any RO chip can be used

Václav Vrba, Institute of Physics, Prague CoaXPress - Emerging communication standard for for machine vision applications. - Serial communication standard over standard coaxial cable. - High data throughput, downstream up to 6.25 Gbps. - Asymmetric, upstream 20 Mbps. - Provides 13 W of power. - Trigger signal - 4 ns resolution. - Low cost, no royalties. - Just one coaxial cable! AIDA annual meeting,Vienna, 26th March 2014 7/17

Václav Vrba, Institute of Physics, Prague Can CoaXPress be used in HEP experiments pixel detectors? AIDA annual meeting,Vienna, 26th March 2014 8/17
9
Václav Vrba, Institute of Physics, Prague CoaXPress for pixel detectors: - CoaXPress is frame based, good for X-ray imaging applications. Readout with zero suppression (vertex detector) is possible, but user needs to implement wrapper protocol on top of CXP. - FPGA soft-core available for a reasonable price. - CoaXPress needs a PHY ASIC (EQC062T20 ~25$), radiation hardness yet not characterized. - Currently no rad hard IP cells for direct ASIC integration.

Václav Vrba, Institute of Physics, Prague Final layout of interface card - 12 copper layers (6 signal, 4 GND reference, 2 power) - FLEX-RIGID technology - class 7 PCB, no buried vias AIDA annual meeting,Vienna, 26th March 2014 12/17
13
Václav Vrba, Institute of Physics, Prague CoaXPress daughter board Motivation - Main interface card PCB contains no physical communication layer. - Main interface card PCB can be extended via daughter board. - Daughter board implements physical layer of communication bus. - Communication standards possible - CXP, Ethernet, USB, PCIe... - Daughter board is simple to redesign, cheap & fast to manufacture -> we are flexible. CoaXPress daugther board designed in May 2013 - Implements CoaXPress PHY, 1 lane 3.1245 Gbps - JTAG debug interfaces - Main system power connector - Debug GPIOs, Reset button, debug LEDs,... - 6 layers PCB.
