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.
The VSC7969 provides filtered bias for MSM and PIN photodetectors; applications using an APD photode-
tector must supply bias separately. The VSC7969 also provides a photocurrent monitor whose output is linearly
proportional to the input photocurrent.
The VSC7969 can operate from a single +3.3V supply or a +5V or -5.2V supply. The VSC7969 is offered
in die form and in a 16-pin plastic thin-shrink small outline package (TSSOP-16). A fully tested TO-46 outline
packaged receiver with a photodetector is also available.
