ADC Module, 2 channels, 80MSPS @ 12bit; Sundance Digital Bus interface


s380aSMT380A offers a integrated solution for medium-speed Dual channel Analogue to Digital data collection and is an upgraded version of SMT380. The single width Module has two AD6645s from Analog Devices Inc. which are 14-bit ADCs with a 80MSPS sampling rate. All necessary functions, including track-and-hold (T/H) and reference are included on chip to provide a complete conversion solution. The converters are interfaced to a Xilinx Virtex-II FPGA that controls them and also provides the data-paths for the digital signals.

The data is routed to two 16-bit Sundance Digital Buses, using two Sundance High-speed Bus connectors. The control of the ADCs is done with the help of a Sundance ComPort.


  • Two 14-bit ADCs AD6645 sampling up to 80MHz. AC coupled
  • Single width module.
  • Two Sundance High-speed Bus (SHB) connectors.
  • Two 20 MBytes/s communication ports.
  • Low-jitter system clock.
  • Xilinx Virtex-II FPGA (XC2V1000-4).
  • 50-Ohm analogue inputs, external triggers and clocks via MMBX (Huber and Suhner) connectors.
  • User defined pins for external connections.
  • Compatible with a wide range of Sundance SHB modules.
  • TIM standard compatible


Ideal for flexible system architectures and specifications IF Radar Sampling, Base-band Radar Sampling, Spectrum Analysers, Digital Radio Receivers, Multi-channel Receivers and Cellular/PCS base stations.

The XC2V1000 Xilinx FPGA has 1 million gates and Sundance uses approx. 1/3 of a million for controlling the converters and rest can be used by the OEM customer for doing pre-processing on the data or for other custom controls.
