2xADC 125MSPS 14bit, 2xDAC 500MSPS 16bit

s950 The SMT950 is a single width expansion TIM that plugs onto the SLB and incorporates 2 Texas Instrument Analog-to-Digital Converters (ADS5500) and one Texas Instrument dual-channel Digital-to-Analog Converter (DAC5687). The SMT950 implements a comprehensive clock circuitry based on a CDCM7005 chip that allows synchronisation among the converters and cascading modules for multiple receiver or transmitter systems as well as the use of external clocks. It provides a complete conversion solution and stands as a platform that can be part of a transmit/receive base station. External Triggers are also available.

ADCs are 14-bit and can sample at up to 125 MHz. The DAC has a resolution of 16 bits and is able to update outputs at up to 500MHz. All converters are 3.3-Volt.


  • Two 14-bit ADCs (ADS5500 – TI) sampling at up to 125 MHz
  • One 16-bit, 2x-16x interpolating dual channel DAC (DAC5687 – TI)
  • One SLB connector
  • Single width expansion module (mezzanine module)
  • On-board low-jitter clock synchronizer
  • One external clock and Two triggers via MMCX connectors (Huber Suhner)
  • External reference clock for synchronising and cascading modules
  • Analogue Inputs/Outputs via MMCX (Huber Suhner) connectors for connection to 50-Ohm sources/loads


The SMT950 can be used for Intermediate-Frequency (IF) sampling architectures, cellular base stations such as CDMA or TDMA, baseband I/Q systems, wireless communication systems, Instrumentation, etc.
