Gen5 MCIO to U.2 Breaker Module

Gen5 MCIO to U.2 Breaker Module

Part Number: QTL2804 / QTL2805

Product Details

Gen5 PCIe requires a rethink of test equipment configuration. The Gen5 MCIO to U.2 breaker module allows you to test a U.2 drive direct from an MCIO based Host card:  SerialCables stock suitable Host Cards

Perform full hot-swap and fault injection with the latest GEN5 PCIe SFF/U.2 drives.

The Gen5 MCIO to U.2 breaker module has full control over power, data (dual port) and present pins, allowing simulation of any possible hot-swap scenario. Individual control of each signal, pin bounce and high-speed glitching combine to increase the number of test cases you can perform greatly. ‘Driving’ is available on some sideband pins. This allows a range of additional tests to drive signals high/low rather than just disconnecting them. The ‘+Triggering’ version has an additional MCX trigger IN/OUT to sync with external test equipment.

Power for the drive must be provided from an external 12v source. Power and control can be provided by either a USB or from a separate QTL1260 interface kit.

NOTE: We recommend evaluating this product in your test system before purchase


  • Automate full hot-swap of a GEN5 PCIe SFF drive, direct from an MCIO enabled host card
  • Simulate failures, intermittent faults and more
  • Improve test coverage while decreasing duration
  • Ideal for bench testing, debugging, and evaluation
  • Scales from 1 to 100+ drive modules in a test system.


  • Supports PCIe SFF drives up to 32GT/s
  • Individual control over power, present, sideband and PCIe data signals
  • Driving and monitoring of selected sidebands
  • 1us timing resolution on all switches
  • 100ns pin-bounce resolution on all switches
  • 50ns PRBS or user-sequenced glitch pulses on all lines
  • Used standalone with USB control OR via a Torridon controller
  • Requires 12v supply for drive, via Quarch PPM or external PSU (not supplied)



This is the basic module.


This version includes external triggering IN/OUT via SMA cables to allow connection to an external analyser or similar.
