ADC Module; Dual Channel 1GHz, 8-bit ADC;


s391The SMT391 is a single width expansion TIM that plugs onto an SLB base module such as SMT338-VP7-5 (Virtex-II Pro),SMT398-VP (Virtex-II Pro) or SMT368 (Virtex4 FPGA)

The SMT391 is a single width TIM module. It is capable of sampling two analogue inputs at 1 GSPS with a resolution of 8 bits. An Atmel duel channel ADC (AT84AD001) performs the analogue to digital conversion.

The Xilinx FPGA (Virtex II-Pro or Virtex 4 for SMT368) on the base module is responsible for handling data going/coming to/from one of the following destination/source: TI converters, Comport (TIM-40 standard), Sundance High-speed Bus (SHB), Memory on some base modules (DDR or QDR) and RocketIO SerialLinks (RSL). These interfaces are compatible with a wide range of Sundance’s modules.

The ADC used on the SMT391 has changed slightly from the one we were using originally. To see the differences please read this document (Replacing AT84AD001B with AT84AD001C)



  • Dual channel ADC (Ideal for I & Q channel applications)
  • 1GHz sampling frequency
  • 8 Bit data resolution
  • Custom Clock and Trigger inputs via external connectors
  • 12 months warranty


Direct RF/IF processing or Direct RF down-conversation can be built with the SMT391 as a stand-alone Module or used in a array of DSP Modules for more performance needed in radar/sonar systems. The SMT391 is comparable to a ultra high-performance Digital Oscilloscope and could be used for evaluating the AT84AD001converter for such applications
