The HXT5112A 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.

Key Features

  • 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
  • 10 mA Average and 10 mA Modulation current max.
  • 15mA burn-in current max.
  • InfiniBand QDR/FDR compliant
  • 100G Base-SR10 compliant
  • Solder bump version available

Applications List

  • IEEE 802.3ba Ethernet transceivers
  • Infiniband QDR & FDR active cables
