Test and Measurement Systems

Test and Measurement systems, which include general purpose oscilloscopes, spectrum & logic analyzers, function & signal generators and application specific test equipment as well as instrumentation, are characterized by the demand for more system flexibility, increasing complexity, and physical system size shrinks with each successive generation.

These trends drive the need for ever-increasing isolator performance and integration. Silicon Labs' digital isolation solutions uniquely meet the critical safety, performance, and PCB area challenges of high performance test and measurement systems.

Test and measurement applications require galvanic isolation for voltage level translation and safety compliance. As signal bandwidths and data rates increase, many test and measurement systems require space-saving isolation that can deliver fast propagation delays and low jitter performance over a wide temperature range. Optocouplers fall short in the areas of speed, jitter, and PCB area.

Application Requirements  Silicon Labs Solution 

Safety - Protect low voltage system circuitry

Performance - Eliminate noise ground loops during high speed data transfer
  • Si84xx digital isolators offer data rates at 150 Mbps across the widest temperature range (-40 to +125 °C), making them suitable to replace octocouplers.
  • Si84xx devices offer 2x better jitter performance than competing devices, minimizing data transmission erros and bit-error-rates.

Reliability - Minimize the impact of common mode noise that leads to ADC sampling error

  • Si84xx exceptional ESD performance enables the highest reliability in harsh application environments: 4 kV HBM, 2 kV CDM and 400 V MM.
