ADN2526:  11.3 Gbps Active Back-Termination Differential Laser Diode Driver

Product Description

The ADN2526 laser diode driver is designed for direct modula-tion of packaged laser diodes that have a differential resistance ranging from 5 Ω to 50 Ω. The active back-termination in the ADN2526 absorbs signal reflections from the TOSA end of the output transmission lines, enabling excellent optical eye quality to be achieved even when the TOSA end of the output transmission lines is significantly misterminated. ADN2526 is an SFP+ MSA-compliant device, and its small package and enhanced ESD protection provide the optimum solution for compact modules where laser diodes are packaged in low pin-count optical subassemblies.

The modulation and bias currents are programmable via the MSET and BSET control pins. By driving these pins with control voltages, the user has the flexibility to implement various average optical power and extinction ratio control schemes, including closed-loop or look-up table control. The automatic laser shutdown (ALS) feature allows the user to turn on/off the bias and modulation currents by driving the ALS pin with a LVTTL logic source.

The product is available in a space-saving 3 mm × 3 mm LFCSP specified from −40°C to +85°C.

Applications

  • SONET OC-192 and SDH STM-64 optical transceivers
  • 10 Gb Fibre Channel transceivers
  • 10 Gb Ethernet optical transceivers
  • SFP+/XFP/X2/XENPAK/XPAK/MSA 300 optical modules
