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. The  
superlative edge-rate and drive current of the VSC7990 enables efficient design of an OC-192/STM-64 trans-  
mitter using directly modulated laser diodes. A two-chip OC-12 to OC-192 optical transmitter can be easily  
implemented using the VSC7990 and the VSC8171 10Gb/s MUX/CRU.  
Applications  
• OC-192/STM-64 @ 2.488Gb/s to 10.7Gb/s  
• 10Gb/s Serial Ethernet
