Introduction  
The VSC7927 is a single 5V supply, 2.5 Gb/s laser diode driver with direct access to the laser modulation  
and bias FET’s. Laser bias and modulation currents are set by external components allowing precision monitor-  
ing and setting of the current levels. Data density outputs are provided to allow the user to adjust the laser bias in  
high unbalanced data applications. Clock and data inputs are differentially terminated to 50 Ohms.  
Applications  
• SDH/SONET @ 622Mb/s, 1.244Gb/s, 2.488Gb/s  
• Full Speed Fibre Channel (1.062Gb/s)
