The Industry's First 40 Gbps Differential Switch


Designed for true differential signal multiplexing, is changing the paradigm for testing next-generation high-speed ICs

Menlo Microsystems, Inc. (Menlo Micro), announced the formal qualification and production release of the MM5600.  This new product is a unique double-pole/double-throw (DPDT) switch providing the industry’s highest performance and data rates for high-speed differential switching applications, including next-generation artificial intelligence (AI), machine learning (ML), GPU/CPU, data center and cloud-based applications, as well as automated test equipment (ATE) device interface boards and high-speed computer peripheral interfaces.

The MM5600 DPDT switch offers high-speed operation from DC to 20 GHz or 40 Gbps, significantly outperforming conventional electromechanical (EM) relays and solid-state switches. The MM5600 provides a best-in-class differential switching solution for high-speed digital applications based on the latest PCI Express standard, PCIe Gen 5, which doubles interconnect speeds over the PCIe 4.0 specification (32 Gigatransfers per second versus 16 GT/s). The MM5600 switch also can be configured for single-ended operation for RF and microwave applications. Its flexible configuration enables internal differential crossover capabilities, greatly simplifying board routing.

Menlo Micro’s MM5600 represents the culmination of several important industry firsts:

  • Fast switching: The MM5600’s ultra-fast switching speed (< 10 µs operation time and < 2 µs release time) is 1000x faster than EM relays, enabling reduced test time and lower cost-of-test.
  • Reliability: The MM5600 provides unmatched reliability and can operate with more than three billion switching cycles, resulting in reduced downtime, maintenance and cost and a 1000x longer lifetime compared to conventional EM relays. 
  • Compact design: The MM5600’s small-footprint/low-profile design (8 mm x 8 mm x 1.6mm QFN package) provides a 90 percent reduction in size over conventional EM relay solutions. This significant reduction enables more parallel tests and easier top and/or bottom routing.
  • Power efficiency: The MM5600 operates at less than 0.08 mW, a 99 percent reduction in power consumption compared to EM relays, making it the most energy-efficient high-speed DPDT switching solution available.
  • Leading IP3 linearity: The MM5600 achieves an IP3 linearity of more than +90 dBm with a power handling capability of +33 dBm, enabling large reductions in distortion and delivering up to a 10,000x improvement over existing EM relays and solid-state switches. IP3 is the figure of merit in determining how much distortion a switch will introduce into a system, impacting the quality of transmitted or received signals.
