PHASE DRIVE-Half of 9614 polarity-reversing line driver feeds pair of Hewlett-Packard HCPL-2602 optically coupled line receivers through coax cable. Cable-grounding switches A and B change performance Closing only switch B enhances common-mode rejection but reduces propagation delay slightly. Closing both switches optimizes data rate. Schottky diodes at receiver inputs improve data rate, NAND flip-flop at output greatly improves system noise rejection in split-phase termination of line．－ Optoelectronics Designer's Catalog 1977, Hewlett-Packard, Palo Alto,CA,1977,p158－159.
