    Hello,
    
 
    I am looking for a driver for direct-modulation of a 1550 nm VCSEL (Cylindrical TO package, manufactured by Raycan). 
    I noticed AD product: ADN2531 and its evaluation boards: EVAL-ADN2531-NPZ , EVAL-ADN2531-NTZ. 
     
     I have the following questions that I will be grateful if you could answer: 
      
     1)      Is this driver suitable for the 1550 nm Raycan VCSEL? If not the optimal, Could you suggest a model more suitable for this VCSEL? 
     
     2)      What is the difference between the two evaluation boards? 
     
     3)      Is there a datasheet or some details on the evaluation boards?
     
     4)      Can I order samples of the ADN2531 driver and of the evaluation board?
     
    Thank you, 
     
    Amos

      Dear Amos,
      
 
      Thank you for sharing us your questions. To better understand your questions,
      
 
      would you please send me the mentioned VCSEL laser datasheet for a review?
      
 
      Both ADN2525 and ADN2531 devices are 11.3G capable, DML drivers.
      
 
      They sink both BIAS and IMOD currents from the VCSEL laser diode. 
      
 
      The major differences are based on the devices. Please see the Isupply difference below:

      Yes, you can order ADN2531 device samples and the EVB.
      Please contact ADI local sales office to get these samples.
      
 
        
      
 
      Both ADN2525 and ADN2531 datasheets are available from ADI
      public website. For example, you can have the ADN2525 from link: http://www.analog.com/en/fiberoptic/laser-drivers/adn2525/products/product.html
      
 
        
      
 
      We have application notes for these 10G LDD EVBs. Please send
      us your email contact information so that we can forward you the required EVB application
      note information.
      
 
           
      
 
      Hope these are useful to your evaluation. We are looking forward to working with you.
