VSC7979,VSC7999
11.3 Gb/s Transimpedance Amplifiers with Photocurrent Monitor and Input Slicing Adjust
G E N E R A L D E S C R I P T I O N :
The VSC7999 and VSC7979 are 10.7 Gb/s - 12.5 Gb/s high performance,
low power transimpedance amplifiers designed for use in optical
communication systems. The devices are intended for use with a PIN
or an APD photodetector, and are capable of amplifying input currents
over 2.5 mA with low duty-cycle distortion and with little total jitter
change. The VSC7999 and VSC7979 offer 9kohm and 3kohm differential
transimpedance respectively, eliminating the need for an additional
post-amplifier. The outputs limit to a typical differential value of
600mVp-p, increasing the dynamic range of the system by reducing the
possibility of exceeding the input voltage range of the transceiver
device. The VSC7999 and VSC7979 also allow compensation for fiber
non-linearities such as dispersion and EDFA non-linearity.
