66215 FIBER OPTIC SCHMITT-TRIGGER WITH TTL OUTPUT/SMA HOUSING PRELIMINARY DATA Mii OPTOELECTRONIC PRODUCTS DIVISION ALL DATA ON THIS SHEET IS PRELIMINARY AND SUBJECT TO CHANGE Revision - 5/25/01 Features: Applications: • • • • • • • Industry standard SMA style connector High input sensitivity less than 2 uW Data speeds to 200 kbps NRZ Spectrally matched for LED’s in the 850 to 880 nm range Short haul data Link Mobile Communications Local Area Networks 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.
