Provides automatic laser control without the need for expensive temperature calibration.Sept 18, 2003 - Analog Devices - The ADN2870 3.3-Gbps laser diode driver (LDD) is fully compliant with the Small Form Factor Pluggable (SFP) Multisource Agreement (MSA) and digital diagnostics (SFF-8472) specifications. It is the only SFP compliant LDD to feature dual loop control of average power and extinction ratio. This feature enables automatic laser control without temperature calibration and look up tables resulting in significant cost advantages.
The ADN2870 is appropriate for modules that serve SONET OC-48, SDH STM-16, 1X and 2X Fiber Channel and Gigabit Ethernet.
Pricing and Availability
Samples for the ADN2870 will be available in October 2003. It is priced at $6.95 per unit in 1,000-piece quantities.
