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 single power supply with a maximum power dissipation of 300mW. A PIN photodiode or APD can be connected and separately biased to provide optimal performance. The VSC7969 provides filtered bias for MSM and PIN photodetectors; applications using an APD photodetector must supply bias separately. The VSC7969 also provides a photocurrent monitor whose output is linearly prop...
