Self‐timed p‐i‐n‐hbt ppm receivers

Abstract

AbstractAn original analysis and results are presented for the sensitivity and self‐timing of a hybrid p‐i‐n, heterojunction bipolar transistor pulse position modulation (p‐i‐n‐HBT PPM) strategy at 622 Mbit/s and λ = 0.85 μm. The results indicate a significant performance improvement over a comparable p‐i‐n‐HBT PCM system. The proposed strategy can find application in optical signal distribution at high bit rates in areas such as optical back planes and multiprocessor systems. The self‐timing of the hybrid is addressed and original results are presented for the extracted slot clock timing variance and the associated jitter wrong slot error (WSE) probability, resulting in specifications on the optimum PPM order, fiber bandwidth, and phase‐lock loop (PLL) bandwidth under self‐timing. © 1994 John Wiley & Sons, Inc.
