The HXT42100 is a low power, Direct Modulated Laser (DML) driver for CLR / LR optical applications that supports data rates up to 28Gbps and optical reach up to 10km. In conjunction with an individual DFB laser diode, the device handles the complete digital-to-optical conversion, including a CML input stage with equalization, laser driver IBIAS, and IMOD current drive control and supervision. Designed for direct DC-coupled anode drive of the DFB laser diode for cost-effective and compact assemblies. Available in die form.


  • Supports Modulation / BIAS currents up to: IMOD = 60mAPP and IBIAS = 60mAPP
  • 2.5 V to 3.3V Voltage Supply operation
  • Programmable Input Equalization
  • Input Signal Detect (SD) with Squelch
  • Programmable Input Polarity Inversion
  • Programmable Pulse Width Adjustment
  • Programmable Laser Modulation Current Amplitude, Peaking, and Peaking Duration
  • Integrated Temperature Sensor
  • Interrupts with User selectable Mask control
  • Laser Disable for IMOD and IBIAS
  • 2-wire interface control and symmetric pad design maximize module design flexibility
  • QSFP MSA Compliant
