6U cPCI 64-Channel Isolated Analog to Digital Converter Board
 

Preliminary

PDF print version of this specification : A4 or Letter

The 64-Channel Isolated Analog to Digital Converter (ADC) board provides 64 high-speed digitally isolated inputs. Each channel features a sample rate of 100 kSps. A Field- Programmable Gate Array (FPGA) is used to provide access to the digital data over the PCI bus.

I/O channels to system isolation is 2 500 V RMS.

The board conforms to the PICMG 2.0 (R3.0) 6U CompactPCI standard.

Architecture

An FPGA is used to control and read the data from the analog to digital converters and provides the PCI Interface. High-speed digital isolators are used to isolate the system side bus from the analog inputs.

Features
  • high number of Analog Inputs
  • programmable inputs
  • Air-Cooled and Conduction-Cooled versions
  • Commercial, Industrial and Ruggedised grades
  • wide range input (+/-10 V)
  • high sample rate of 100 000 samples per second
  • high-speed digital isolation
  • Board Identification switch
  • wide bandwidth (up to 50 kHz)
