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 50Ω and

must be AC-coupled. 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 two-chip OC-12 to OC-192 optical trans-

mitter 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
