HXT8201

The HXT8201 VCSEL driver is a key component for compact, robust, low-power optical transmitter modules. In conjunction with the VCSEL, 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 118mW per channel while delivering 5mA average and 5mA modulation current
  • User selectable: Input equalization, output peaking, polarity inversion, interrupt masks
  • Compatible with common cathode and isolated VCSEL arrays
  • 2-wire, I2C compatible control interface
  • Up to 10mA IAVG and 10mA IMOD current
  • Suitable for TO Can applications
  • SFP MSA compatible

Applications List

  • 100G to 25G Ethernet SR fan-out modules
  • 25G Ethernet SR / 32G Fibre Channel
  • InfiniBand 25G EDR transceivers / AOC
  • Proprietary multi-channel optical modules
