GENERAL DESCRIPTION
The VSC7997 and VSC7998 are 10.7Gb/s high performance transim-pedance amplifiers designed for use in optical communication networks including Sonet OC-192/SDH STM-64 and 10G Ethernet fiber links. The devices are intended for use with a photodetector and are capable of amplifying inputs currents of up to 2.2mA with low duty cycle distortion. The VSC7997 and VSC7998 are pin and functionally compatible. The designer has the flexibility to choose between the 5KW (VSC7997) and the 1.4KW (VSC7998) differential transimpedance as required by system architecture and performance.
