Fiberoptic interface


Posted on Sep 5, 2012

An op amp is used to interface between a fiberoptic system and the MOS SCR to multi-cycle, half-wave control of a load. This receiver has two complementary outputs, one at a quiescent level of about 0.6 V and the second at 3 V. By adding a 4.7 V zener in series with the return bus, the effective VqC becomes 5.3 V and also the 0.6 V output level is translated up to about 5.3 V.

This level is compatible with the reference input (5.9 V) of the single-ended powered op-amp acting as a comparator.
