General Description
The VSC7969 is a 3.125Gb/s transimpedance amplifier IC with a built-in limiting amplifier, a signal detect feature and a photocurrent monitor. The VSC7969 does not require any external electrical components in the construction of a high performance optical receiver such as for SONET/SDH applications. The analog output is
a differential signal with a minimum amplitude of 200mVp-p (single-ended). The VSC7969 operates with a sin
gle power supply with a maximum power dissipation of 300mW. A PIN photodiode or APD can be connected
and separately biased to provide optimal performance.
