Packard HCPL-2602 optically coupled line receiver handles high data rates from shielded, twisted-pair, or coax cable fed by 745140 line driver, Reflections due to active termination do not affect performance. Peaking capacitor C and series resistor R can be added to achieve highest possible data rate. C should be as large as possible without preventing regulator in line receiver from turning off during negative excursions of input signal. Highest data rates are achieved by equalizing tPLH(propagation delay time to low output level) and tPHL (propagation delay time to high output level).- Optoelectronics Designer's Catalog 1977, Hewlett-Packard, Palo Alto, CA, 1977, p 158-159.
