DESCRIPTION
The
66215
series, receiver contains an 18 mil X 18 mil active area photodiode coupled to a trans-impedance amplifier that
converts the light generated to a voltage level. This voltage is compared to an internal threshold of a schmitt trigger circuit that
provides a sharp output transition even for slowly varying light levels. Optical switch point is typically less than 2
µW.
An
internal output buffer stage provides true TTL logic levels with rise and fall times typically in the 6-10 ns range. The receiver is
designed to interface with multi-mode optical fibers from 50 to 100 microns. These LED’s convert electrical current into optical
power that can be used in fiber optic communication. This receiver may be screened to specific customer requirements or
MIL-PRF19500.
