VSC7878
10 Gbps Linear Transimpedance Amplifier
G E N E R A L D E S C R I P T I O N :
The VSC7878 is a 10.3 Gbps transimpedance amplifier (TIA)
designed for use in 10GBASE-LRM optical communication
networks. The VSC7878 is intended for use with a PIN or APD
photodetector and operates over a wide dynamic input range while
maintaining excellent linearity. The gain varies to maintain linear
amplification for input signals up to 2 mA maximum. A DC
compensation circuit reduces the penalty of low extinction ratio
signals. The VSC7878 also provides photodetector power supply
filter components and has a photocurrent monitor output.
