General Description  
The VSC7990 is a single +5V or -5.2V supply, 10.7Gb/s laser diode driver with direct access to the laser  
modulation and bias FETs. Laser bias and modulation currents are set by external components allowing preci-  
sion monitoring and setting of the current levels. Clock and data inputs are differentially terminated to 50 Ohms.  
The superlative edge-rate and drive current of the VSC7990 enables efficient design of an OC-192/STM-64  
transmitter using directly modulated laser diodes. A 2-chip OC-12 to OC-192 optical transmitter can be readily  
implemented using the VSC7990 and the VSC8171 10Gb/s MUX/CRU.  
Applications  
• OC-192/STM-64 @ 2.488Gb/s to 10.7 Gb/s
