The HXT6112 VCSEL driver array is a key component for compact, robust, low-power optical transmitter modules. In conjunction with the VCSEL array, the chip handles the complete digital-to-optical conversion, including CML input, laser driver, drive control, and supervision. Standard silicon technology and a small number of additional components allow for cost-effective and compact assemblies.


  • Low power consumption of 46mW per channel while delivering 5mA average and 5mA modulation current
  • Compatible with common cathode and isolated VCSEL arrays
  • 2-wire interface control and symmetric pad design maximize module design flexibility
  • 10mA Average and 10mA Modulation current maximum
  • 15mA burn-in current maximum
  • InfiniBand QDR/FDR compliant
