  1. 12-BIT, 500 MHz ADC Module for the KOTO Experiment The University of Chicago Mircea Bogdan Chicago, Oct. 09, 2009

  2. 12-Bit, 500 MHz ADC ModuleBlock Diagram • 4 ADC channels on board serviced by one Stratix II FPGA; • After SERDES, data moved with 125MHz. Mircea Bogdan Chicago, Oct. 09, 2009

  3. 12-Bit, 500 MHz ADC ModuleAnalog Channel Each ADC Channel can be stuffed in differential or in single ended configurations, on the same PCB. This Schematic shows a single ended configuration with -1V offset. Components marked “space” are not installed. Mircea Bogdan Chicago, Oct. 09, 2009

  4. 12-Bit, 500 MHz ADC Module Specifications • 4 Channel, 12-BIT, 500 MSPS ADC: • ADS5463 by TI; • 6U VME64x; • Front Panel LVDS I/Os: • RJ45 (same as the 14-BIT ADC): • 3 Inputs; • 1 Output; • 0.1” Right Angle Header: • 4 Inputs; • 4 Outputs; • Front Panel LVTTL I/Os: • 8 I/Os configurable; • Front Panel Optical I/Os: • 2 Inputs 2.5 to 3.125 Gbps; • 2 Output 2.5 to 3.125 Gbps; Insert 4 ADC Channels in this Area. Old 14-BIT, 125 MSPS ADC: Mircea Bogdan Chicago, Oct. 09, 2009

  5. 12-Bit, 500 MHz FADC ModuleConclusions The Digital part of the 4-Channel 500 MSPS Module is very similar to the 16- Channel 125 MSPS Module. Many Logical Blocks will be reused in this new design. Design process as short as possible. Mircea Bogdan Chicago, Oct. 09, 2009
