SMT950

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.
