28G – 12 Channel VCSEL Driver

The HXT8212 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.

Features

  • Low power consumption of 113mW 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
  • Up to 10mA average and 10mA modulation current
  • QSFP MSA compliant
